Need your brain scrambled? Here’s a list of logical and mathematical paradoxes

I’m not exactly sure how I ended up on the Wikipedia page listing dozens of paradoxes of infinity, but I did. And I read the whole damn thing and it kind of hurt my brain a little, so I thought I’d share.

Know your awesome engineers of history: Charles Proteus Steinmetz
The great mathematician and engineer Charles Proteus Steinmetz, a contemporary of Albert Einstein, Nikola Tesla and Thomas Edison stood only four feet tall and was crippled and bent by kyphosis but was a giant in his field. One day, when Henry Ford’s, electrical engineers couldn’t solve a problems they were having with a gigant generator,Ford called Steinmetz. Upon arriving, Steinmetz rejected all assistance and asked only for a notebook, pencil and cot. Steinmetz listened to the generator and scribbled computations on the notepad for two straight days and nights. On the second night, he asked for a ladder, climbed up the generator and made a chalk mark on its side. Then he told Ford’s skeptical engineers to remove a plate at the mark and replace sixteen windings from the field coil. They did, and the generator performed to perfection.Henry Ford was thrilled until he got an invoice in the amount of $10,000. Ford acknowledged Steinmetz’s success but balked at the figure. He asked for an itemized bill.
Steinmetz responded personally to Ford’s request with the following:Making chalk mark on generator $1.
Knowing where to make mark $9,999.
Ford paid the bill.

It took one Japanese guy seven years to draw this “unsolvable” maze

Twitter user Kya7y recently posted a picture of a hand-drawn maze her dad made that took him seven years to complete. The maze has sparked interest from both the art world and the math world, because just look at it… it’s gorgeous and intriguing. Kya7y says her father claims the maze is unsolvable, but someone’s going to rig up some clever piece of technology that will solve it. Or not. Maybe a thousand years from now.

Will we ever run out of new music?

YouTuber Vsauce raises some food for thought— humans have been making music for almost our entire existence, there is only a finite range of notes that humans can hear and only a certain number of combinations (even if it it a huge number) in which those notes can be arranged. And today, we’re making more music than ever before, so will there come a point when we completely run out of new songs?

Anxiety about math can cause real, physical pain

Some people love math, but for many others, “hate” isn’t a strong enough word… something that causes fear and anxiety and even physical pain.
