and they're left behind, and they feel that the future doesn't need them at all.Now what I see a lot of people trying to do is to figure out some way to decelerate technology,is to figure out some way to use legislation and laws to decelerate the technology so we don't get left behind.

The future used to be written in laws in Washington, D.C.Now the future is written in code, in Silicon Valley.And so there has to be a new deal, a new agreement, a new social contract between Big Tech and human beings.

It looks something like this.Now at first glance, this looks very similar to the electric scenario where we have a positive and negative charge, but this picture doesn't look at what's going oninside the magnet. So if we reveal what's inside and you see that these lines actually continue, but now they point from south to north.

But Thomson realized that the magnetic vector field B could be defined as the curl of some other vector field, the magnetic vector potential A.Now even though they're both vector fields, it turns out that A is often much easier to work with than the magnetic field itself,much like the other potentials V and phi, - Thomson was showing there was a kind of underlying mathematical structure one could use

Thank you to Richard Behiel for inspiring this approach.Now, if you look closely at the original phase term, you see A and phi, the magnetic and electric potentials.So watch what happens if we add a magnetic vector potential that points in the same direction as the electron is traveling.

And a similar thing would happen if you change the electric potential phi.Now, this by itself, I think wasn't shocking to most physicists.Just as you would always use the potentials to make the math easier, that's also why you use it in the Schrodinger equation.

In the middle of these two beams is a tightly coiled wire known as a solenoid.Now, solenoids have an interesting property.When you run a current through one, it produces a strong magnetic field inside the coil and a very weak field outside the coil.

And here at this point, they intersect.Now since electrons behave as waves, the waves from the intersecting beams overlap and produce an interference pattern, bright fringes with gaps in between them.The exact pattern depends on the phase of each of these waves.

And that's exactly what's happening here.Now take a closer look at the vector potential.In the space the upper beam passes through, the potential points in the opposite direction as the beam.

- And that's showing, throwing no shade on their colleague who did these cool experiments.Now, previous experiments relied on turning a magnetic field on or off, but Tonomura's team took on a different approach.

- And that's showing, throwing no shade on their colleague who did these cool experiments.Now think about what this interference pattern should look like.

- And that's showing, throwing no shade on their colleague who did these cool experiments.Now here are the results from Tonomura's experiment.

- And that's showing, throwing no shade on their colleague who did these cool experiments.Now we can actually run this.

- And that's showing, throwing no shade on their colleague who did these cool experiments.Now you can imagine, okay, let's add a constant to this.

- And that's showing, throwing no shade on their colleague who did these cool experiments.Now atoms like electrons are also governed by a wave function.

Inhuman monsters. - So who were they, the Vikings, coming from the north? How did they think of the violence that they were doing?- Now, that's a very good question because... and it brings up a central problem, of looking at the Vikings, which is the story is almost always told fromsomebody else's perspective largely from the pens of those they're attacking.

We're entering into an era that we call planetary intelligence, where new capabilities and action can happen at the speed of change.Now, my co-founder Will was on this spot in 2014 and he shared with you all our dream.What if we could image the whole world every day?

50%.Now, let's see what this looks like at the speed of change.Let's go to Kenya.

Thomas Jefferson wrote one of the most consequential documents in American history.Now, the Declaration of Independence wasn't perfect. Just like the guy who wrote itand the country it created weren't perfect, either.

And glutamate is what's important in fast communication in your brain.Now what’s interesting is that ketamine targets glutamate, but it doesn't activate it.It blocks it. So why would blocking fast communication have any beneficial effect?

They were very clever, but brittle.Now, in 2025, they can compete with the best of us at the International Math Olympiad, which is the premier precollege math competition.But the interesting bit is the following.

as surely as a calculator performs arithmetic.Now, Leibniz thought this would revolutionize humanity.With a system like this, if two people had an intellectual conflict, they would resort to logic and not rhetoric to resolve it.

In some sense, it was meant to be a universal calculator for truth.Now, Leibniz was a bit of an optimist.He thought this would take a small group of people five years to build, and he was off by several centuries.

With the use of technology like AI and simple behavior changes, we could bring joy back in travel.Now imagine if we were to make the entire travel industry's objective, the airlines, the hotel, the travel tour operators,to bring joy to both residents as well as the travelers.
