The Biggest Ideas in the Universe is a series of videos where I talk informally about some of the fundamental concepts that help us understand our natural world. Exceedingly casual, not overly polished, and meant for absolutely everybody.

This is Idea #13, “Geometry and Topology.” Yes that’s two ideas, and furthermore they’re from math more than from science, but we’ll put them to good use. In particular we look at Riemannian (non-Euclidean) geometry, and a kind of topological invariants called “homotopy groups.”

Before we get into non-Euclidean geometry, we have to know: what even is geometry? What’s up with the Pythagorean math cult? Who was Euclid, for that matter? And what the heck is the 5th Postulate?

Probability and statistics on Khan Academy: We dare you to go through a day in which you never consider or use probability. Did you check the weather forecast? Busted! Did you decide to go through the drive through lane vs walk in? Busted again! We are constantly creating hypotheses, making predictions, testing, and analyzing. Our lives are full of probabilities! Statistics is related to probability because much of the data we use when determining probable outcomes comes from our understanding of statistics. In these tutorials, we will cover a range of topics, some which include: independent events, dependent probability, combinatorics, hypothesis testing, descriptive statistics, random variables, probability distributions, regression, and inferential statistics. So buckle up and hop on for a wild ride. We bet you’re going to be challenged AND love it!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We’ve also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Mathematics describes the real world of atoms and acorns, stars and stairs, with remarkable precision. So is mathematics invented by humans just like chisels and hammers and pieces of music? Or is mathematics discovered—always out there, somewhere, like mysterious islands waiting to be found? Whatever mathematics is will help define reality itself.

Mathematicians get very minimal recognition for the work that they do. Their contribution to history created a big impact on the world, but most people don’t know who they are. But we will change that and honor the world’s most brilliant minds on this list.

What people do not know is that even before engineers can make advancements in technology or scientists can develop formulas and medicines to cure, they first throw several equations. Thanks to the concepts laid out by these famous mathematicians, scientists can now do their important work. You might disagree but mathematics plays a big role in changing the world, one solution at a time. .

Benjamin makes numbers dance. In his day job, he’s a professor of mathematics at Harvey Mudd College; in his other day job, he’s a “Mathemagician,” taking the stage to perform high-speed mental calculations, memorisations and other astounding mathematic stunts. It’s part of his drive to teach math and mental agility in interesting ways, following in the footsteps of such heroes as Martin Gardner.

TEDxOxford is organised by University of Oxford students, aiming to bring together the young minds of tomorrow’s world with the movers and shakers of today. TEDxOxford is kindly sponsored by Neptune Investment Management – http://www.neptunefunds.com

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event.

MATHCOUNTS is the largest tournament-style middle school math competition in the United States. In addition to bringing math enthusiasts together, it also provides an opportunity to learn how to think creatively about math by trying challenging questions. To introduce the type of math in this activity, we shared a free MATHCOUNTS mock test as an online mini-course. It simulates a Chapter Sprint Round, with complete solutions provided: https://daily.poshenloh.com/courses/2020-mathcounts-mock

This video explanation is for one of the more difficult combinatorics problems there, and shows how cleverly you can count! It is pulled out from that free online mini-course for coaches, teachers, or parents to preview. Interested students should take the mini-course instead of watching this video, because it is better to try the problem in the context of the mock test first, before seeing the explanation.

The Daily Challenge with Po-Shen Loh (https://daily.poshenloh.com) is a fun and systematic tour of middle school competition math, designed for students who already understand math at school, but are newcomers to extracurricular math. Through an original teaching style that develops creative thinking, students discover the rich world of math that they can build from their foundation. This online course series supports the development of the social initiative expii.com. .
