If Nikola Tesla had to Pitch Products to Modern VCs

If Nikola Tesla had to Pitch Products to Modern VCs

Nikola Tesla was ahead of his time. In many ways, he is still ahead of our time. Some of his inventions and discoveries are still baffling scientists today (notwithstanding the conspiracy theory that his technology has always been understood but was suppressed, but that’s a different story). If he were around today trying to raise funds for his wireless energy concept, there’s a good chance that he would be met with insurmountable obstacles. The money is controlled by people who are not adequate in their understanding of how such amazing inventions can operate in this world and are driven by the…

How the universe is defined

How the universe is defined

Time to put your thinking caps on and attack a larger issue. Actually, it’s about as large of an issue as you can imagine: the universe. What is it? On the surface, it’s an easy question to answer. The universe is everything, right? Not so fast. What about the future? Is that part of the universe? Ideas such as mathematics – do they qualify as parts of the universe or do they only exist in our minds? If they exist in our minds, does that still qualify as existing somewhere and therefore these ideas are part of the universe. The folks over at Minute Physics take us on a very brief exploration of what the universe…

The conclusion to an immovable object meeting an unstoppable force will surprise you

The conclusion to an immovable object meeting an unstoppable force will surprise you

Leave it to the folks at Minute Physics to give enjoy thinking harder than you really want to for under four minutes. That was the case yet again as they tackled the age-old concept of an immovable object meeting an unstoppable force. Rather than just take it all at face value, they dig deeper into the concept, bringing out both the fallacies as well as the brilliance hidden within the question itself. If you have a minute (well, 3 and half, actually), we strongly encourage you to get educated. Let’s do science! …

Should we teach the wrong things to children because it

Should we teach the wrong things to children because it's easier to understand?

It’s no secret. We love Minute Physics. They have a way of taking complex ideas and dumbing them down to our level so that we don’t have to go to school to study quantum mechanics to understand some of the most important components that affect our daily lives. This time, they did something they normally don’t do. They made us think, not just about the science at hand but more importantly about a moral efficiency challenge facing many schools. Some concepts are hard to understand. There are false but “close enough” concepts that often cover the ideas and give us a decent understanding of what is happening…

Gravitational time dilation in layman

Gravitational time dilation in layman's terms

Understanding the physical natural of time has been something that physicists have struggled with and debated over since before Einstein brought into mainstream scientific reasoning. It’s difficult for those without a degree in physics to comprehend moving at different speeds based upon the relative position and speed of travel of the observer, but it’s been proven time and time again (pun intended). This video by Chuck Missler at Koinonia House breaks it down for us nicely. Rather than talking over the listener, he explains it in hypothetical and real world terms that won’t put (most) people…

In case you ever wondered about traveling through a hollow earth...

In case you ever wondered about traveling through a hollow earth...

Normally, VSauce puts out some amazing minutephysics videos that spark the imagination and enlighten us in ways the world and universe work. Other times, the information is relatively useless but interesting nonetheless. This video falls into the latter category. What would happen if you drilled from one side of the earth through the center to the other? That’s what they try to explain here. …

Ultimate geekness exemplified by Don Pettit and his yo-yo in space

Ultimate geekness exemplified by Don Pettit and his yo-yo in space

There is a lot more physics involved with yo-yos than most people know. Take one into space and operate it with the skill and precision of NASA astronaut Don Pettit and you get 6 epic minutes space chat, yo-yo tutorials, and advice on picking up girls with yo-yo tricks. …

Understanding relativity in 4 minutes or less

Understanding relativity in 4 minutes or less

For over a century, people have tried to cope with understanding Einstein’s special theory of relativity and his famous equation, E=MC2. There have been long videos and visualizations that attempted to dumb down both the process that Einstein used to come up with the theories and the way that our minds can wrap themselves around them. Here, the good folks at Minute Physics did as their namesake implies: they explained it to us in a pair of 2-minute videos that (should) make it easier to comprehend. First, let’s look at the special theory of relativity: Now for the fun part – understanding E=MC2:…

Fire is cool in theory

Fire is cool in theory

Humans take fire for granted. The reality behind the science of fire is actually pretty interesting. Whether looking at the chemistry behind it, the quantum mechanics that drive it, or the simple but amazing concept of lighting a candle in space, fire can be a very stimulating subject. That’s the thought in this physics-minute (and a half) about fire. Amazing stuff. …
