So, I have a feature on my website where every week people submit hypothetical questions for me to answer, and I try to answer them using math, science and comics. So for example, one person asked, what would happen if you tried to hit a baseball pitched at 90 percent of the speed of light?

Align:start g’day and welcome to take math Channel today we are going to be having a look at his how to quickly multiply two three-digit numbers together and this little method you see here is a really really good one we’re going to use it to multiply two three-digit numbers but you can actually expand

I want to work a variety of problems here that involve similar expressions, but each problem has a different instruction. Let’s take a look at our first one. Our first problem here we want to solve the equation 8x – 5 = 0. Okay, no problem. I’ll add 5 to each side using the Addition

The speed of light is 299 792 458 meters per second. Exactly. No seriously. By coincidence? No let me explain. The most successful measurement of C was done in 1972 using laser interferometry… laser interferometry. Sounds familiar? Let me help you, LIGO. Laser Interferometer Gravitational-wave Observatory. Yes the technology used to measure the speed of

Translator: Mohammed Basheer Reviewer: Nadine Hennig Good afternoon, ladies and gentlemen, my name is Art Benjamin and I am a “mathemagician”. What that means is I combine my loves of math – or I should say maths – and magic to do what I call “mathemagics”. But before I get started, I’ve got a quick

G’day and welcome to the TecMath channel. In this video today we are looking at the fast way of multiplying two two digit numbers together….so let’s go! First of all we’ll see if you can multiply some numbers together I’ll give you a question which is twenty-one times thirty one. I’ll give you six seconds

Is there a border we will never cross? Are there places we will never reach, no matter how hard we try? Turns out there are. Even with science fiction technology, we are trapped in our pocket of the Universe. How can that be? And, how far can we go? We live in a quiet arm

Hey, Vsauce. Michael here. About 6 percent of everything you say and read and write is the “the” – is the most used word in the English language. About one out of every 16 words we encounter on a daily basis is “the.” The top 20 most common English words in order are “the,” “of,”

Hello. In this video we are going to characterize one aspect of light waves by looking at what frequency and wavelength are and how they are related to the speed of light. First we need to understand what frequency is, frequency’s relationship to wavelength, how frequency is measured, and finally looking at how frequency and

Hey Vsauce! Michael here. Down here. But which way is down? And how much does down weigh? Well, down weighs about a hundredth of a gram per cubic centimeter. It is light and airy which makes it a great source of insulation and buoyancy for water birds but if you let go of down… It
