YOUR FOOD IS ALWAYS OUTSIDE OF YOU

(Some Ideas About Space But Definitely Not Time)

ABSTRACT:

I’m going to, in an accessible way, cover some mathematical and physical ideas that I think are important or at least pretty cool. (CHILL. OUT.) You probably spent a lot of time in grade school factoring polynomials or whatever. I don’t care about that. I want to talk about why orbits work, what happens in 5-D, why the World Series is slightly better than a coin toss, databases are broken forever, truth itself is wrong, and what happens if an infinite number of buses roll up at your house. Or some subset of that.

I’ll cover three or four discrete topics, so don’t worry if you get lost; you’ll be following along again in a few slides. Any equations will be supplementary only- you won’t have to understand them to get the general idea.

A few weeks ago I was contacted by the folks at **Free Radical Media** to see if I would be willing to be a guest in their fledgeling podcast network. I checked out some of their work and really liked what I found, so I nervously agreed – I’ve never been a guest on a podcast before.

We ended up discussing a myriad of topics focused on mathematics, education, and some of the problems associated with our centralized systems as well as some of the solutions available to us at the moment.

It was a very fun experience and I would like to thank Eric and Patrick for having me as a guest. Below you will find the podcast.

Why is Math Important?

… Read the restMention time travel at a nerd party, and other guests will immediately respond with a grim conundrum: What happens if a time traveler goes back in time and kills one of his ancestors? This is the “Grandfather Paradox.” In a simulated environment, a team of mathematicians tested the paradox, and made a remarkable discovery: In time travel simulations, at least, history repeats itself.

The Grandfather Paradox makes a mess of time travel. A murderer kills his ancestor, preventing his own birth, thereby preventing the murder, thereby being born, thereby committing the murder, and so on. To observe it, a team of researchers, led by Martin Ringbauer, created a simulation. Instead of firing up a DeLorean to 88 miles an hour, they sent photons through a “closed timelike curve,” or CTC. The photons are paired up so that one follows the other.

“What are the odds?” I said upon discovering an old classmate in the lobby of the very same hotel in St. Thomas where I had just checked in. “And look, you’re reading Leibniz too!” My old classmate was carrying a transcript of Leibniz’s letters to Clarke, and I had a copy of his letters to Arnauld in my bag at that very minute. Just as we were marveling at the incredible coincidence, in walked the professor under whom we had both studied Continental Rationalism — including a good deal of Leibniz — at university! In his bag was a biography of Wilhelm Gottfried Leibniz.

“This is too much,” I said. “The odds of the three of us arriving here, in the US Virgin Islands, on St. Thomas, in this hotel lobby, on April 4th at 3:00 pm, all carrying books on Leibniz…the odds are astronomical! This can’t be a coincidence. … Read the rest

From the file of lost mathematics systems of remote cultures, via Scientific American:

Binary arithmetic, the basis of all virtually digital computation today, is usually said to have been invented at the start of the eighteenth century by the German mathematician Gottfried Leibniz. But a study now shows that a kind of binary system was already in use 300 years earlier among the people of the tiny Pacific island of Mangareva in French Polynesia.

The discovery, made by analysing historical records of the now almost wholly assimilated Mangarevan culture and language and reported in Proceedings of the National Academy of Sciences, suggests that some of the advantages of the binary system adduced by Leibniz might create a cognitive motivation for this system to arise spontaneously, even in a society without advanced science and technology.

Q:“If you could give us all a one word piece of advice for our own science storytelling, what would it be?”Bill Nye was the first to reply with,

“Algebra, learn algebra.”Neil deGrasse Tyson follows with,‘Ambition’.Lawrence Krauss with,‘Passion’.Neal Stephenson with,‘Empathize’.Richard Dawkins states that sinceempathizehas already been taken, he will choose‘Poetry’.

Jason Padgett, 41, sees complex mathematical formulas everywhere he looks and turns them into stunning, intricate diagrams he can draw by hand. He’s the only person in the world known to have this incredible skill, which he obtained by sheer accident just a decade ago.

“I’m obsessed with numbers, geometry specifically,” Padgett said. “I literally dream about it. There’s not a moment that I can’t see it, and it just doesn’t turn off.”

Padgett doesn’t have a PhD, a college degree or even a background in math. His talent was born out of a true medical mystery that scientists around the world are still trying to unravel.

I’ll be the first to admit that my math skills are rudimentary. I’d go so far as to say they’re borderline non-existent. To quote that famous plastic scholar Barbie, “Math is tough!” If you can do math, especially anything from algebra on up, you’ve got my admiration – maybe even my fearful reverence. You’re like the first caveman who mastered fire to me. You don’t have to worry about me coming to your door with pitchfork in torch in hand. However, the same can’t be said of certain groups of Christian fundamentalists. According to BoingBoing’s Maggy Koerth-Baker, some of these guys are waging war against higher mathematics, particularly something called “set theory”. Check it out:

… Read the restSome of these folks get very touchy about the idea of infinity. Mark Chu-Carroll is a software engineer at foursquare and a math blogger. Unlike me, he was already aware of the fundamentalist objection to set theory, because he’s actually had people show up in his comment section railing about how the theory is an affront to God.

The year was 1943, and the Pentagon had a problem. They'd poured millions of dollars into a new voice encryption system -- dubbed the "X System" -- but no one was certain how secure it was. So the top brass called in Claude Shannon to analyze their code and -- if all went well -- to prove that it was mathematically unbreakable. Shannon was a new breed of mathematician: A specialist in what's known today as information theory. To Shannon and his fellow theorists, information was something separate from the letters, numbers and facts it represented. Instead, it was something more abstract; more mathematical: in a word, it was non-redundancy...
