The Great Albert Einstein… in a cartoon
Ah! Yes. Albert Einstein. The famous scientist and mathematician who’s last name I can never spell correctly! Yes. Today, I’m going to teach you about Albert Einstein. But not about him. I’m going to talk about his refrigerator.
What?! Albert Einstein invented a refrigerator! Yes. Why yes he did.
The Einstein–Szilard, or Einstein refrigerator is an absorption refrigerator that has no moving parts, operates at constant pressure, and requires only a heat source to operate. Pretty cool, right?
Did you know? Albert Einstein was fascinated by what happened to a Berlin family who had been killed when a seal in their refrigerator failed and leaked toxic fumes into their home. Pretty strange reason to get fascinated, am I right? (But no one came blame Einstein. He changed our lives!)
Einstein’s refrigerator was patented in the 1930s and doesn’t use greenhouse gases and can be used without electricity! Do we still use it now? I have no idea!
Isaac Newton Himself
Calculus. You might’ve heard it from someone, you might know it as some kind of math, but you might not know that Newton discovered it!
Many people know Isaac Newton for his discovery about his three law’s of motion, but he also invented calculus! I bet you didn’t know that! It impacted the world when he invented calculus in 1665. We take this for granted nowadays, but what Newton did hundreds of years ago is astonishing, considering now, many people take ages to learn it!
Calculus has uses in physics, chemistry, biology, economics, pure mathematics, all branches of engineering and much more!
Newton’s focus on gravity and laws of motion are linked to his breakthrough in calculus. Newton started by trying to recount the speed of a falling object. When he did, Newton found out that the rate of a falling object increases every second, but there was no currently existing mathematical explanation for this!
Newton immediately started working on this, and he figured out that when using calculus, he could explain it! So this is how Isaac Newton discovered calculus.
Okay. So who is this Ohm guy? His full name is Georg Ohm. (And yes. It’s spelled Georg. That’s not a typo. He has such a strange spelling name in my opinion. No offense Ohm!)
He was born on March 16, 1789, in the university town of Erlangen, Bavaria. His little brother, Martin Ohm, also became a famous mathematician! Johann Wolfgang Ohm, his father, was a locksmith. Maria Elizabeth Beck, his mother, was a daughter of a tailor. She died when Georg was ten.
“Ohm’s Law states that the current passing through a conductor is proportional to the voltage over the resistance,” says ducksters.com.
This may sound very confusing. I’m a little bit confused myself! But it can be written in a simple formula: I = V/R. I is currents in amps. V is voltage in volts. And R is resistance in ohms.
Voltage divided by current is resistance. Resistance times current equals voltage. Just like math. I don’t like math.
Hey! Ohm is not a thing. He’s a person! But an ohm CAN be defined as “an electrical resistance between two points of a conductor,” as said by Wikipedia.
So I guess when you say “ohm”, it could mean a person or a thing! Kinda like a noun. Haha.
