Humans have been designing and innovating for 100,000 years, but nature has been doing so for 4.5 billion years. Turns out we still have a lot to learn from nature, and biomimicry is the science of using nature to inform innovative design. Here are some great examples of this new and maybe world-changing design philosophy.

With more countries flying to space than ever and a private space race in full swing, the legalities around space and space resources are still very much up in the air. There are currently only a few treaties that guide space activity and they are woefully outdated. So that begs the question - who owns space?

Supervolcanoes are bigger than you think, and there are more of them than you think. There are, in fact, eight supervolcanoes around the world that have changed the geography of continents and caused mass extinctions. What are these volcanoes? What causes them, and most importantly, could we survive one?
Today we take a deep dive into one of the most destructive forces on the planet. And if you think that supervolcanoes have been over-hyped... trust me, they haven't.

What do you "see" in your mind's eye? Is it as real as looking at a photo? Or do you not see any images at all? It turns out there are 3-5% of the population who don't have the ability to form images in their heads. It's a condition called "Imagination blindness" or Aphantasia, and it was only recently discovered.
Along with Aphantasia is the opposite end of the spectrum, Hyperphantasia, where the mind's eye is so vivid, it's hard to distinguish between what's real and what's imagination.
It opens up a lot of questions about how we see and perceive our world.
Here are links to the tests to determine where you fall on the spectrum:

The aluminum-air battery has made headlines on the promise of giving a car up to 1500 miles of range, which would be amazing. But there's one big catch - you can't recharge it.
Today we talk about the pros and cons of the aluminum-air battery, how it works, what "mechanical charging" is, and whether there's a real case to be made for their widespread use.

Here we go again. I recently covered the Victorian Era but today I want to point out the incredibly weird health and beauty practices that Victorians were into back in the day.
As I say in the video, Victorian medicine was a mix of terrible old ideas and terrible new ideas, from people drinking radioactive water to eating ground-up mummies our transition to the modern medical system we see today hit some interesting bumps in the road.

We all know you need oxygen to live. But why? What happens to oxygen in our bodies? Why does it keep us alive? And maybe most importantly, why does it slowly kill us? In today's video, I explore the process of respiration, how it's weirdly similar to fire, and why we rely on one of the most corrosive elements in the universe to survive. It gets weirdly existential.

Blue Origin has stated their long-term goal is to move all heavy, polluting industry to space. But what would that look like? How could we get there? And maybe the biggest question... why?

With the Inspiration4 mission in the books, hot on the heels of Blue Origin and Virgin Galactic launching their first crewed missions, we've seen a bit of a backlash against this new space race. So today I just wanted to share my opinion on why space travel is important and the framing we've seen around these flights and these companies is misguided.
All opinions are mine (as of this recording anyway). Disagreements welcome.

Ancient history is as much myth as it is history. So it's sometimes hard to know who from our history was real or just a mythical character in stories. Here's a few that are worth taking a look at.

The Victorian Era was an age of new discoveries and technologies that changed everything about the way we live. It basically created the modern world as we know it. But that time of transition also led to some very, very weird ideas and dangers that seem baffling today.

NEOM is Saudi Arabia's tentpole project in their Vision 2030 initiative to help move the Kingdom away from an oil-based economy and rely more on technology and tourism. It has some ambitious goals, like being 100% sustainable, moving all transport underground, and even glowing beaches. But the most noticeable thing about the project is the fact that the city will lie on a 100-mile line serviced by a hyperloop-style high speed train system.
But is it all it's cracked up to be? Let's take a look.

The race to the moon was always more about dueling superpowers than the spirit of exploration. And because of that, enormous risks and creative leaps were made to reach their goal. For that and many other reasons, the Apollo program was one of the most insane ventures ever undertaken, and here are 10 reasons why.

With Artemis 1 stacking right now and the first launch planned by the end of the year, the moon is getting more attention than we have seen since the 1960s. The plan this time is to stay in a permanent moon colony, supported by mining operations on the lunar surface. But what could we mine there? And why will it be necessary for our future moon ambitions as well as interplanetary travel?
There's gold in them there craters. Let's take a look.

Carl Sagan is an absolute legend and a hero, and his book Contact and the movie it's based on is phenomenal. HOWEVER... we examined the central conceit of the story - that aliens pick up our radio signals and return a message with instructions to build a machine - and look at the stars inside the 100 light-year bubble around Earth where our radio waves have traveled. And the potential of this happening... Well, it isn't good.
Sorry Carl.

Up to 70% of amputees claim to feel pain in their missing limbs, and we're still not completely sure why. Some of the theories range from nerve damage to crossed wires in the brain to a redrawing of the mind's map. And some new therapies involving simple mirror illusions and cutting edge technology are helping amputees live less painful lives. And it's also making us question the very nature of reality.

On June 15 of 2009, the body of a middle-aged man was found on Rosses Point Beach in County Sligo, Ireland. He had no identification on him, no passport, even the tags had been removed from his clothes. Over the following days, as authorities reviewed his activity with security camera footage, they found that he went to great pains to dispose of his personal effects without anybody seeing. This was a man who wanted to disappear completely. And he was almost successful. But one random thing went wrong and turned him into one of the biggest internet mysteries of all time.

Human experiments are conducted ethically all the time. But throughout history, especially during wartime, horrifying human experiments have been conducted that are little more than an excuse for cruelty and torture. Here are some of the worst examples.

The Bermuda Triangle has held our collective attention for decades. This area of the ocean is blamed for countless missing ships and planes, spawning theories as wide-ranging as time/space vortexes, methane bubbles, the City of Atlantis, and, of course, aliens.
But is there a rational explanation for all the weird phenomena reported in the Bermuda Triangle, or is it more of a pop culture phenomenon? Let's take a look.

The Big Bang Theory of the origin of the universe is pretty much set in stone - or so you would think. Turns out there are several problems with the Big Bang model, some of which are answered with Inflation Theory; the idea that in the first trillionth of a second the universe expanded from a singularity to something the size of a basketball, then slowed its expansion.
But there is another idea, one based on string theory and gives the possibility for the universe to renew itself over and over again in cycles. It's called the Ekpyrotic Universe Theory. And it's weird. Real weird.

What makes a person join a cult? What makes a person give up their families, their life savings, even take their own lives in the service of a cult? We often think of cult members as weak-minded or sheep, but the fact is, cults work by employing psychological tactics that work on everybody. And that may be the scariest thing about them.

The Quantum Suicide experiment (ironically also known as quantum immortality) is a product of the many-worlds interpretation of quantum physics, which says that quantum particles never leave superposition, just that our perspective makes it look to us like the wave function collapses.

Space shades are often touted as our last hope if our climate change situation gets too out of control. If we can't keep carbon emissions down, we could just block the sun. I hear this option get thrown out very casually, but I've never seen a realistic look at what that would look like. How big would it need to be? How much would it cost? Wound it even work?

Jupiter is made of 90% hydrogen and 10 percent Helium and other chemicals. Its clouds include layers of ammonia ice, ammonium sulfide, and water vapor, but underneath the cloud layer, things get really weird.
The pressure forces the hydrogen together until it takes on some unique properties, first a supercritical state that is neither gas nor water, and the other a metallic hydrogen state where the flowing hydrogen conducts electricity that ultimately powers its massive magnetic field.
Oh, and it will kill you.

Moore's Law states that computer processing power will double every 2 years, but we may be reaching a limit to this exponential growth. Thankfully, some new technologies may be turning that around.

===================
SUMMARY:
Gordon E. Moore was one of the co-founders of Intel and first proposed was came to be known as Moore's Law, which predicted that computer power would double every 2 years.
For nearly 50 years, the industry kept pace with this prediction, but in recent years there's been a slowdown. 2 main reasons are heat and the quantum tunneling effect that occurs at the atomic scales.
Some of the technologies that have been theorized to break through this barrier include:
Graphene processors. Graphene carries electricity far better than traditional silicon processors, but is currently very expensive to produce.
Three Dimensional Chips. Some manufacturers are experimenting with 3-D chips that combine processing and memory in one place to improve speed.
Molecular transistors. Transistors that use a single molecule to transfer electricity.
Photon transistors. These take electrons out of the process entirely and replaces them with laser beams.
Quantum computers. These long-hyped machines could perform multiple calculations at once by using the superposition of quantum particles to process information.
Protein computers. These use folding proteins to make calculations.
And finally, DNA computers. DNA is the perfect data storage device, allowing scientists to store 700 terabytes of information in only one gram. But it can also be used in logic gates and are being tested in a processing capacity.

Transcript:
So back in January of 2016, Musk was speaking at SpaceX’s Hyperloop pod competition, when he said this:
“It’s a really simple and obvious idea and I wish more people would do it: build more tunnels. Tunnels are great. It’s just a hole in the ground, it’s not that hard. But if you have tunnels in cities you would massively alleviate congestion and you could have tunnels at all different levels – you could probably have 30 layers of tunnels and completely fix the congestion problem in high-density cities. So I strongly recommend tunnels.”
But it was something he just kinda said off the cuff and nobody but the most ardent Musk-watchers paid any attention to.
He claims to have built a machine that can dig tunnels for transportation 500 to 1000% more efficiently than current boring machines.
And his logic is that people in cities live and work in a 3D space, in vertical buildings that can house more people. But our city transportation is on a 2D plane, meaning all these vertically packed people are now crammed into a horizontal space.
By creating a 3D transportation grid, we can alleviate the congestion and drive like civilized human beings.
Now, there are a couple of criticisms of this plan, one is that this idea’s been around for over a hundred years, it’s called subways.
And subways are great for densely packed urban areas like New York but for cities like LA, or Dallas for that matter, where things are spread far apart, not so much.
For example, it’s a 20 or 30 minute drive just to get to my closest light rail station, at that point, I might as well just drive the rest of the way. It’s just not practical.
But underground highways under strategic high-traffic arteries could make a big difference. And reducing the time cars are idling in traffic could cut down on pollution as well.
The other criticism is that building tunnels is not nearly as easy as it sounds, even with a giant high-tech earthworm machine doing all the work.
Obviously in urban areas there’s all kinds of things we’ve put under the ground in terms of sewers, gas lines, telecommunication lines and so forth.
But we at least know where those are, what we don’t know is other things like pockets of gas, unstable rocks, hidden fault lines, and so forth.
But… I’m sure all those things will be addressed before any large-scale tunneling begins in LA., there’s a mountain of bureaucratic red tape to get past before that happens.
Which should put completion around the Fall of… never.
A side benefit of this tunnel machine would be for SpaceX’s future Mars colonies, since boring underground would be the best protection against cosmic rays.
Now this is of course nowhere near Elon’s first foray into transportation, I mentioned earlier his hyper loop competition, well, he just hosted another competition in January.
27 teams entered designs, of those, 3 were picked to actually run, and of those, two won awards, one for design, and the other for speed, maxing out at 90 kilometers per hour, or 55 miles per hour.
That’s a far cry from the 900 miles per hour predicted for the hyper loop, but it’s early yet, and it’s only a one-mile stretch of track, so it’s probably not getting up to top speed.

Automation and artificial intelligence are already causing massive disruptions to commerce and industry all over the world. Economists warn that in the next 10 years, 30% of jobs could go away due to technological advancement. An unemployment rate that would be worse than even The Great Depression. How does society react in the face of this kind of change, and what can we do to position ourselves to be ready for the changes to come? In this audio version of my YouTube video, I discuss what I think are the best options.
