3-D Printing Comes To Life

So my daughter is graduating high school, but is already taking a class in 3-D printing. 

(This little guy pictured here was made experimenting in the class and was a precious gift from her.)

Already prophetically envisioned in Star Trek as "the replicator," this technology has been around in primitive trial form since the 1980's.

In 3-D printing, alloyed material is successively layered under computer control to make complex shapes and products.

It makes traditional 2-D printing (on paper) look like rubbing two sticks together to build a fire (circa the paleolithic period of mankind thousands of years ago). 

The promise of 3-D printing for advanced manufacturing is absolutely incredible.

The Wall Street Journal describes how NASA researchers and engineers are working toward using 3-D printers in space to "make bricks suitable for airtight buildings and radiation proof shelters" simply using the sand already on Mars. 

Moreover, the astronauts on their journey may be eating pizza from these printers as well (except for the sand, but still probably better than MREs--Haha).

Already objects have been printed "19 feet long...stone-like building blocks weighing one-and-a-half ton each"!

In the future, 3-D printers could be sent in advance to planets we look to colonize and "lay down landing pads, roads, and shelters" in preparation of our arrival.

These printers could even build working replicas of themsleves or "swarms of self-assembling construction robots" boosting our capacity for even more building.

Moreover, technology is in the works to recycle from 3-D printing by melting down the printed products back into material that could be reused for new printing projects.

On Earth, where we have long been drawing down our natural resources as well as polluting our environment, the prospect of going to other worlds where their are new resources and we actually have the ability to use them constructively is humanity's chance for a whole new chapter of life beyond. ;-)

3-D Printing Comes To Life

Live With The Eternal In Mind

I really like this saying.

I heard it this weekend on a popular television show at the burial of one of the characters. 

"What you see is temporal; what you don't see is eternal."

Everyday, we think we are living in the "real world," but this is just our mortal experience, one constrained by our senses and the dictates of time and space.

However, beyond this mere earthly experience and existence is the eternal G-d. 

Perhaps, we can take comfort and live a life of meaning, if our existence in the temporal world is always with the eternal in mind. ;-)

Live With The Eternal In Mind

Escalator To Another Time And Place

So everyday, I pass this broken escalator in the Washignton D.C. Metro system.

Does it even look like an escalator anymore--all opened up with it guts hanging out like this. 

Anyway after a while, the days turn into weeks, and the weeks into months, and this escalator is still b~r~o~k~e~n! 

After a while, you almost start to think that this escalator was never a working one and was always broken, just like this...that time has essentially passed this one by and given up here. 

But lo and behold, I was reminded by a conversation today with a good friend that according to quantum physics, time is not linear, but instead all exists simultaneously across the time-space continuum (something like parallel universes).  

It was funny, because honestly, I have been thinking this for years (or maybe it was just yesterday or tomorrow) that time is really just an illusion...all time is one. And it's just that our mortal minds need to experience it sequentially. 

However to G-d, there is no time or space...it's all just one, and he is one and perfect. 

For us though, at least in this universe, this cruddy escalator continues to be out of service, but perhaps in another one, it will be working again...hope, indeed. ;-)

Escalator To Another Time And Place

Stop The Nuclear Threat

Before we get too rosy on the State of the Union...

Fascinating article in Forbes on the threat from nuclear armageddon. 

- The Russians nuclear missile survivability is improving with missiles "equiped with four warheads that can be independently targeted."

- Typical yield is 500 kilotons--"equivalent to half a million tons of conventional explosives."

- The impact of a single nuclear explosion is that it heats the targeted areas to a "few thousand degrees."

- If/when exploded over a major city, "everything within a one-mile radius is destroyed, heavy damage extends to three miles, and fires will be widespread out to five miles."

- People at ground zero will be annihilated immediately "by the blast effects or a wind-spread firestorm...(initial wind speed 700 mph)" 

- Those father from the epicenter will "linger longer before succumbing to the effects of prompt and delayed radiation."

- Due to the magnetic pulse, "electronic devices will be shut down for a hundred miles in every direction."

- How many long range nuclear missiles does Russia have? Over 2,000 (that are known)!

- Just 50, would leave every American city with over half a million people, "uninhabitable."

Now think about the Mullahs of Iran targeting, America, "The Great Satan," should they get this capability.

And do you think a Congressionally, bipartison endorsed, deadline-triggered sanctions on Iran should be vetoed or championed by the administration to stop this threat? 

May G-d bless us with the wisdom and strength of character to see through the delay tactics and subterfuge of our enemies and remove this real threat from us.

As to the Russians' strategic nuclear arsenal, we better get moving along on Reagan's Star Wars Strategic Defense Initiative--because 2,000 is a heck of a lot of incoming! ;-)

Stop The Nuclear Threat

We Didn't Make History

A sincere congratulations to the European Union for the epic landing of a probe from the Rosetta spacecraft--the first such landing on a comet.

They did this with a landing area of just 550 yards in diameter and away from deep crevices, large boulders, and sharp peaks--it is amazing!

Their European space scientists are exclaiming and rightfully so, "We made history today."

The problem for us is that we--the U.S.of A.--didn't!

Yes, we landed the first man on the moon in 1969 and we haven't done it again since 1972.

I remember in grade school, with great pride and wonder, watching the first space shuttle taking flight--that was in 1981.

Since then, we had the horrific Space Shuttle Columbia disaster (2003), followed by the retirement of the shuttles altogether (2011).

Now, we rely on Russian rockets to bring supplies to the International Space Station and for our military and national security satellites.

Then, just a few weeks ago, we had the explosion of Virgin Galactic's SpaceshipTwo (2014) that is said to have been plagued with problems from inadequate rocket thrust, flight control system issues, and deficiencies in basic structural integrity. 

In the meantime, the Indians have made it to Mars on a dime. 

Where are we as a nation looking to advance into space--where resources and our very survival may someday soon depend?

Just think what those multi trillions of dollars spent (some would say squandered) in Iraq and Afghanistan (now being overrun by ISIS or threatened by the Taliban) as well as for the American Recovery and Reinvestment Act (uh, what did we really accomplish for all that money spent?).

Where we once led, and as children we stood in awe, now we stand in bewilderment and leave our children marveling at the victories and accomplishments of others. 

We can not/must not become complacent or stop investing strategically in our future--we need to act with urgency and commitment again for our nation to succeed.

Time, Our Most Precious Asset

Albert Einstein taught us how this world is governed by space and time. 

Before we are born and once we are gone, space and time no longer apply--we are in G-d's realm.

Time is so important and precious, that even space is constrained by time--i.e. we cannot be in two places at the same time.

When it comes to time, we can never have enough and this pervades every aspect of our lives.

Time, Our Most Precious Asset

Mars On A Dime

So no one can seem to believe that India made it into orbit around Mars for just $74M.  

According to the Wall Street Journal that compares with $671M that it cost NASA (which arrived just 3 days earlier than India's) and the European Space Agency's mission that cost $386M in 2003,

But aside from the Indian's being able to achieve a Mars mission at a tenth the cost of what we did, BBC reported that they also did it $26M cheaper than even the cost of the science fiction movie Gravity with Sandra Bullock about the International Space Station. 

While we clearly go the extra mile and are able to do great things--why does it always cost us so much to get there?

Perhaps, you can say that we are somehow more diligent or careful in our work (i.e. putting a premium on safety) or that it's just the higher cost of labor in this country or that we are early innovators and incur the costs of research and development that others than leverage. 

However, even though we are considered a very wealthy nation, it is fair to ask whether we are managing our wealth with discretion and an eye to the future or do we just take it for granted and are wasteful with it?

With a $3.9 trillion federal government budget (note, this is a full 21% of the entire U.S. economy/GDP), we are talking about some serious money, and we should be getting the most for it.

Unfortunately, the gravy train extends from certain "Beltway Bandit" contractors--e.g. remember the $640 toilet seats, $7,600 coffee makers, and $436 hammers uncovered by the Project on Government Oversight--and apparently all the way to mission Mars. ;-)

Just About Says It All

Story of human civilization in 2 minutes by Joe Bush

History majors can probably add some, but overall completely awesome!

Maybe this is a glimpse of what it's like to have a G-d's eye view of the world--where time and space are inconsequential. 

Looking at this, are we almost at the end or are we just on the verge of a new beginning?  ;-)

Just About Says It All

Panic, Technology To Rescue

Who us panic?

- ISIS is threatening the West with "dangerous new extremism"
- Syria's death toll tops 170,000 with more than 10,000 believed tortured to death. 
- Boko Haram is still abducting young girls (and boys).
- Iran says no deal on nukes. 
- Ebola is "out of control."
- China is emergent as the U.S. pivots east and space becomes militarized with anti-satellite weapons. 
- Russia is resurgent (Crimea is history to Ukraine).
- The national deficit only hints at the true extent of our unfunded liabilities from entitelements.
- The economy is bubbling over the top again, warns Robert Shiller.
- Racial and income inequality continues to divide America (case in point, Ferguson MO).
- Nearly 1 in 3 American adults has an arrest record.
- Almost half the world--3 billion people--live in poverty on less then $2.50 a day. 

Ah, if only technology could solve all our global problems--and this is a big list and not by any means comprehensive.

It's a race of the "world is exploding all over" with technology trying to make it better with more and better information, innovation, productivity, security, and cures.

Almost like the war of good over evil--we may lose the battle, but hopefully (let's pray) in the end, we will win the war. ;-)

Panic, Technology To Rescue

U.S. To Give Up U.S.?

This is just ridiculous already...I mean why do we even bother to try, if as a nation we are just resigned to give up.

1. Russia takes Crimea and the U.S. has "no options," instead of considering a variety of meaningful options--will Putin stop with Crimea, Georgia, Chechnya if there is virtually nothing standing in his way?

2. Syrian civil war goes on for almost 3 years and takes 150,000 lives and the U.S. has "few options," while Russia, Iran, Hezbollah, Saudi Arabia seem to have and be exploiting lots of options.

3. "U.S. to give up Web oversight" since other governments have complained over our "unique influence"--well darn it, we invented the Internet, why shouldn't we capitalize on it?

4. Serious "deficit reduction is dead" even though the national deficit continues to grow and threaten the national security of this country, but there are few acknowledged options for politicians that want to get re/elected, except to continue the runaway gravy train.

5. Space exploration to other planets--NASA shelves it--"Space, the final frontier...to boldly go where no man has gone before," but we're not really going!

6. Defense cuts threaten U.S. military as the "U.S. faces a more volatile, more unpredictable world," and even as China ramps up its military budget by 12.2%.

7. Despite the potentially catastrophic impact that a serious cyber attack would have on the U.S. national security and economy, "the U.S. military is not prepared for cyber warfare"-why are we waiting for the proverbial lights to go out?

8. Outsourcing jobs outside the U.S. has already become cliche--with top U.S. Corporations sending more than 2.4 million American jobs overseas between 2002-2011--as our own labor force participation is now at a 30-year low!

I don't understand what has happened to our national resolve to succeed, to lead, to be a good example in the world.

Why are we in global retreat--instead of steadfastly protecting and growing our national strategic interests in every domain?

We are innovators, entrepreneurs, skilled in every worldly affair, and lovers of freedom and human rights for all, yet we have become gun shy, afraid, and reticent to be ourselves and do what we do best--which is to do what's right, what needs to be done, and to be global leaders in progress toward the future.

If we can't do this, if we have just given up, if we have become ostriches with our heads in the sand--then we haven't just given up on this or that or the other thing--but we have given up on being the U.S. of A.

U.S. To Give Up U.S.?

How Our Colony On Mars Will Get Built

Absolutely amazing development in robotics...

According to the Wall Street Journal, Harvard University researchers have developed autonomous robots inspired by termites or ants. 

They can build complex structures by working in a group or swarm.

Each robot is independent, yet by being programmed with the target structure, they work harmoniously together to build the structure without further guidance. 

They have sensors along with a set of rules that enable them to interact with each other and the environment to get the job done. 

They can even build stairs to enable themselves to get to higher levels of the structure and add the next set of building bricks. 

The robots are 8" by 4.5" with pinwheel tires for traction and are powered by off-the-shelf motors.

"Each robot 'walks around the structure until it sees something that needs to be done and then does it...they can recognize errors and correct them.'"

Perhaps, the robots can not only learn from the termites, but we can learn from the robots. ;-)

How Our Colony On Mars Will Get Built

The Dancer and The Tablet

So we are at this Mediterranean Restaurant next to the beach.

We are sitting outside--it is a little chilly and we cozy up next to one of the fire poles to keep warm.

We weren't eating much; just a drink for our anniversary and something to munch on.

All of a sudden, my wife points to this lady from the next table who gets up and starts dancing provocatively.

You can see the sliver of ocean behind her, the night sky, and the cars and pedestrians are going by behind her.

There are multiple realities going on here:

She is in her own world--dancing to the music, swaying this way and that, and enjoying her femininity. 

On the other hand, the guy she's with is taking a video of her on his tablet computer--he seems more concerned with capturing the moment with his technology than enjoying his girlfriend. 

We are conscientious observers--I sort of wondered if the guy should've been paying more attention to the women who was wooing him than playing with his tablet. 

The other lesson that I can't help reaching is that cameras and microphones are truly everywhere--privacy is a complete myth!  

He is recording her, we are videoing them on our smartphone, and the restaurant is taping all of us on CCTV cameras, and NSA is laughing at us from Fort Meade. 

So if you want solitude, book a flight with Virgin Galactic. ;-)

The Dancer and The Tablet

Going For Gravity

A good friend told me to go see the movie Gravity.

He said, "You'll definitely like it, and make sure you see it in IMAX!"

G-d, I don't recall the last time that I went to an IMAX showing. 

So keeping in the mind the saying, "try it and you'll like it," we went for the $19.00 IMAX 3D experience. 

(OMG, I still remember when movies in NYC were $1!) 

I was hesitant about this movie having heard that there were only 2 characters, and that 1 was Sandra Bullock!

Also, that she was the only one left for the second half of the movie--and I thought how interesting is this going to be?

Okay, I told myself, I'll get excited by the action and destruction in the first half with Clooney and sleep through the second half with Bullock. 

But it was so much better than I anticipated--one of the best movie experiences for me ever!

The IMAX 3D was absolutely amazing...only thing better would've been a massive in-your-face hologram of the whole movie--and I bet this comes one day soon.

The space walks, hurling space debris, exploding space stations and daring escapes was right there and up close in this movie.

I found myself at times reaching my hands out to practically touch the characters--since they seemed that close. 

And Bullocks tears floating in space--were very moving and cool at the same time. 

Bullock is going to win a ton of awards for her performance in Gravity. 

Oh, and one more funny experience was when a lady told this guy in the theatre to hush, and when he didn't listen, she kicked his chair.

But that wasn't the end of it...

After she kicked it a few times, he turned around grabbed her shoe right off of her foot and then threw it at her. 

She ran out of the theatre to get security. 

Security told them both to cut it out, and then I heard the guards outside laughing about these two quarreling theatre-goers. 

Anyway, I didn't sleep a wink in this movie, and enjoyed the whole experience. ;-)

Going For Gravity

For Somebody Who Has Everything

What do you get somebody who has everything? 

Well check this out...

You can actually buy acreage on the moon through The Lunar Registry, "Earth's leading lunar real estate agency."

Based on The Outer Space Treaty, no country can own a celestial resource such as the moon, planet, or asteroid, but this doesn't preclude private entities and individuals from purchasing a "lunar land claim."

The Space Settlement Institute, which "promotes the human colonization and settlement of outer space" is lobbying for the U.S. to recognize these space land claims (PopSci).

According to their website, when you purchase real estate through the lunar registry, "your property ownership is permanently registered by the International Lunar Lands Registry in its annual publication, which is copyrighted and deposited in the United States Library of Congress and with international patent and trademark offices."

You can view available properties here, from the Sea of Vapors ("moon on a budget" for $18.95 per acre--near Crater Manilius) to Lake of Dreams ("most popular" for $34.25 per acre and a special "Sweathearts package with 2 acres side-by-side).

Properties can be viewed at The Full Moon Atlas through The Luna Society.

I found Lake of Dreams by its reference in sector B-4, although I couldn't really tell from the atlas whether this was a place that I'd like to settle down or not. 

In real estate, they alway say "location, location, location"--when you're buying on the moon, who the heck knows? ;-)

For Somebody Who Has Everything

People Needing People

My wife always tells me she needs a lot of personal space--she likes time and focus to do "her thing." 

No one nagging, yapping, coming around, asking for things...just some quiet time for herself.

I can appreciate that--we all need time to think, be creative, take care of personal things, and pursue our own interests. 

At the same time, people need other people. 

When we are done doing our things, we need human interaction, attention, conversation, sharing, touch. 

I saw a few things this week that really brought this home:

1) The Netflix show "Orange Is The New Black" about a young woman put in jail and how she handles all the challenges of being incarcerated with literally a cast of characters.  But in one scene in particular, she is thrown in the SHU (Solitary Housing Unit) and within about a day, she is hearing voices and talking to someone that isn't there. Alone, she crawls up into a ball--like a baby--craving someone to come, anyone. 

2) Visiting the nursing home today, I saw many old people screaming for help. It is a really nice nursing home as far as they go, and the people apparently weren't screaming because of mistreatment, but rather for attention--a human being to be there interacting with them. Interestingly, even when the old people are sitting together, they are still yelling in a sort of helpless anguish being alone, only calming down when a family, friend, or caretaker comes over to them, touches their hand or hugs them, asks about their wellbeing, and shows genuine human caring. Yes, they have real physical needs they call out for help for too, but I think even many of those calls for help--too many and too often to all be for actual needs--are just for someone to come around and pay them attention and be there with them.

3) I remember years ago, seeing some parents put their child to sleep at night. But the child wanted their parent to sit with them and comfort them while they drifted off to sleep. But this parent strictly followed the Dr. Spock guidance that you just let them cry it out, and boy did this little girl cry and cry and cry.  I said to my wife, this is not the right way--it can't be. And I myself always fought that the children should be held and comforted when they cried, not forced at such a tender young age to be alone and "self-sufficient."

While people need time and space for themselves, even the biggest introvert among us needs other people. 

In solitary, people can literally lose their mind--alone, scared, desperate, but solitary doesn't have to be a prison, it can be an emotional and mental condition where people are craving even just a hug from someone who gives a damn.

3-Bedroom Homes on Mars

I am very excited about Bigelow Aerospace's BA-330 space inhabiting module.

The BA-330 is an inflatable, expandable habitat that can be launched into orbit or used to colonize another planet. 

According to Bloomberg BusinessWeek (2 May 2013), the space vessels are inflatable--like a football or car tire.

The inner core is an airtight bladder for living. The outer shell is composed of protective layers of foam and bullet-resistant Vectran fabric. In the center is a metal framework of electronics and equipment.

The "space habitat is folded tightly into the trunk of a rocket for launch, and released in orbit, where is inflated with a breathable atmosphere." 

Internal pressure makes the hull rigid and the up to 40" of layered protective material make the habitat stronger and safer than conventional aluminum modules--and yet can be produced at half the cost!

The modules can be arranged vertically into the equivalent of a three-story home with kitchen, dining room, bedrooms, and gym. 

NASA has plans for one of these modules to join with the International Space Station and to test it for future uses. 

Bigelow wants to be the 1st space landlord renting out dwellings, work environments, and laboratories to tourists, scientists, and companies. "Bring your clothes and your money. We provide everything else."

For only $51M you can travel to the Bigelow Alpha Station--it's first commercial outpost--and enjoy 110 cubic meters for 60 days. 

Someday, these early ventures into space will seen as the pioneers crossing the oceans to discover and settle new far away lands, but the difference will be millions of miles and infinite choices. ;-)

3-Bedroom Homes on Mars

Colonize and Survive

It was interesting to read in Popular Science (12 April 2013) that the famous physicist and futurist, Stephen Hawking, stated that humans would face extinction on planet Earth within the next 1,000 years. 

Hawking says we need to colonize other planets--and I believe that is sound advice. 

While Mother Earth has an incredible ability to rejuvenate and self-heal, let's face it, the planet cannot sustain us forever in our current state.

According to the United Nations, the world population is expected to hit 9.22 billion by 2075, and life expectancy is expected to rise varying across countries from 66 to 97 by 2100.  

Moreover, according to research institution, Transatlantic Academy (May 2012), over the next 10-20 we are likely to see "accelerating demand for most natural resource commodities...increasingly volatile markets, [and] scarcities are likely to be more common." 

In the absence of major technological breakthroughs, increased social equity, and peaceful coexistence on this planet, we will need to find resources outside of Earth and colonize other planets--this is our future.  

Already, as reported by National Geographic (10 April 2013), the administration has funded NASA to capture an asteroid and set it in orbit around the moon  to not only study and develop capabilities to help protect our planet from a collision, but also to eventually be able to mine asteroids for precious minerals. 

As much as we love Earth--although sometimes we don't show it by being gluttonous with its resources, polluting, destroying the ozone, and generally not following sustainable practices--we need to have a "Plan B" whereby we explore for water, food, land, minerals, and energy elsewhere and be ready to make a move to survive another 6000 years and more. ;-)

Colonize and Survive

Eyes Wide Open

This is an interesting video on Plato's Allegory of The Cave. 

It is long-winded, but if you watch a little I think you will get the point.

In the video prisoners who are kept in the dark, chained, and with no real view of the outside world, have a limited perception of what exists out there.

They see shadows, but what is a shadow compared with the reality of true people, places, and things. 

When one prisoner is released outside into the light and the wonders of the world, he sees and experiences the greatness, the complexity, and the beauty of it all. 

The world, he sees, is much more than a shadow on a darkened wall. 

Watching this video, I think how fortunate I am to be able to have an education (and I am actually in a class this week). 

It is wonderful to learn and grow--and have one's eyes opened to all there is out there. 

True, not all the topics that I encounter and learn about are of great interest to me (sometimes, like everyone, I feel like I just want to get some Zzzzzs), but just being exposed to different topics and ways of thinking is a great opportunity in and of itself. 

I think sometimes, how lucky I am to live in the 21st century in an age of globalization, opportunities for advanced education, and all the technology to bridge time and space and see more than many who came before us. 

I imagine that compared to G-d, we are like the prisoners in the cave who only experience and see a minutia of reality, and G-d is out there over us, omniscient. 

Someday, G-d releases us from our mortal bodies and we ascend to heaven to partake of his greatness and then our eyes are truly opened as well. ;-)

Eyes Wide Open

Repair Robots In Space

This is a cool video by the Defense Advanced Research Projects Agency (DARPA) on project Phoenix--which is a robot that can repair satellites in space and re-use components from retired satellites around it. 

Phoenix can intercept, scavenge, and rebuild satellites in space--while orbiting above the Earth at 22,000 miles!

In the corner of the video, you can see progress being made in the lab, and in the main video frame you can see an animated version of how this would actually be put to use. 

Machines working on, building, and repairing machines!

Like the fulfillment of a Terminator-like society, where machines can function with autonomy, eventually learning, self-healing, and even propagating.

I would imagine that these machines can help not only repurpose and recycle material in space to good use and fix things, but also they can clean up the space junk in orbit--similar to street sweeper trucks in Manhattan!

Eventually, these robots will travel to distance worlds--first Mars--to build human colonies and maintain them in inhospitable environments. 

In mythology, Phoenix is a bird that regenerates and is reborn--in this case, this may be the beginning of the rebirth of human civilization throughout the galaxy. ;-)

The Materiality of Super Strength Graphene

Scientific researchers in Britain, Norway and the U.S. are bringing us a major breakthrough in material science—by developing a “super strength” substance called graphene.

According to the Guardian (26 December 2012), graphene has “unmatched electrical and physical properties.” It’s made of an “atom-thick sheet of carbon molecules, arranged in a honeycomb lattice,” and promises to revolutionize telecommunications, electronics, energy industries, not to mention the untold applications for the military.

- Conductivity:  Transmits electricity a million times better than copper
- Strength: The strongest material known to humankind, 200 times that of steel (Sciencebuzz)
- Transparency & Flexibility:  So thin that light comes through it; more stretchable than any known conductor of electricity

Just a few of the amazing uses graphene will make possible (some of these from MarketOracle):

- Home windows that are also solar panels—clear off that roof and yard
- TV in your windows and mirrors—think you have information overload now?
- Thinner, lighter, and wrappable LED touch screens around your wrists—everyone can have Dick Tracy style
- Medical implants and organ replacements that can “last disease-free for a hundred years”—giving you that much more time to be a helicopter parent
- Vastly more powerful voice, video and data and palm-size computers—giving the average person the “power of 10,000 mainframes”
- Both larger and lighter satellites and space vehicles—imagine a skyscraper-size vehicle weighing less than your “patio barbecue grill”!
- Tougher and faster tanks and armored personnel carriers with the plus of an invisibility cloak—even “Harry Potter” would be jealous

The potential is truly amazing, so whomever thinks that the best technology is behind us, better think again. Better yet, soon they’ll be able to get a graphene brain implant to help them realize what they’ve been missing. ;-)
