Why don’t we make scientific laws anymore? Neil deGrasse Tyson and Chuck Nice break down how we went from laws to theories, what the term means in contemporary science, and how there will always be limits to our knowledge of the universe.

More than Neil explaining us things, I get more excited when Chuck gets an idea and Neil agrees with it. It’s like Chuck is representing us mere mortals in front of scientists like Neil.

The universe has no obligation to make sense to you. That’s brilliant.

I need that t-shirt: Einstein had a theory, you have a hypothesis 😂😂 8:40

Should science still use the word “law,” or is uncertainty its greatest strength?

Okay, so... how do I get literally every single person on the planet to sit and watch and internalize this? lol

11:41 Around 3rd century BC, Aristarchus estimated the Sun’s distance by observing the Moon at half phase, when the Earth-Moon-Sun form a right angle at the Moon. He measured the angle between the Moon and Sun in the sky as about 87° (true value ~89.85°) and used trigonometry to estimate the Sun’s distance as the Earth-Moon distance divided by the cosine of that angle, placing the Sun about 19 times farther away than the Moon (actual value ~400). Because the Sun and Moon appear the same angular size, he concluded that the more distant Sun must be much larger, estimating its diameter at about 19 times that of the Moon. The method failed numerically because small errors near 90° cause huge distance errors, but it succeeded conceptually by correctly showing that the Sun is vastly larger than Earth, supporting heliocentrism. He broke the myth based knowledge and followed math, reasoning and experimentation almost 1500 years before Copernicus dusted that book off the shelf.

My physics professor always called Ohm’s Law “Ohm’s Nifty Little Idea”
