Today, I’ll walk you through Arthur Benjamin’s trick.
Once again, here’s a link to his ted talk. He does the trick I’m giving away at around 5 minutes and 42 seconds.

After enjoying Arthur Benjamin doing his mathemagics, I thought I’d give it a try for myself. I wrote a little software and gave it a go. Join me and you’ll find out why I’m not a mental calculator, but that anyone can do it if they know the trick.

Here’s a link to the ted talk in question:

Ep 9: From mnemonic and memory to math and mental calculation

##### From mnemonic and memory to math and mental calculation

You could be better at doing math than you might think. There are methods that allow one to do tricks with numbers that seem just across the street from flat out impossible.

Watch as Arthur Benjamin shows us how one can calculate in ones head, sometimes faster than one could use a calculator.

Approximately 10 minutes and 42 seconds into that first video, he uses some variant or another of the major system in order to hold some numbers in his mind, while he works on others. Have a look at the major system and how it works.

The Major System

Finally, Arthur Benjamin shows us how to do a couple of mental math methods. The tricks are surprisingly easy to use. Impress your friends and scare your neighbors!

Ep 8: Memories and lasers and mice, oh my!

##### Memories and lasers and mice, oh my!

Today’s episode is just to point you at an interesting ted talk. I don’t say much other than that you should check out this link. So, check out this link.

A mouse. A laser beam. A manipulated memory.

It’s about 15 minutes long, and it explains how they used a laser to play with memories within the brains of mice. No, really!

Ep7: Now where did I put…?

##### Now where did I put…?

Today, we examine the method of placing things you wish to remember within a place that you hold in your mind.

For background, here’s a roughly 9-minute ted talk on systems in your brain related to memory, and how your brain keeps track of where you are, or even, where you imagine you are.

##### As I recall

Today is an introduction to Mnemonics—methods you can use to improve your memory.

Here’s a 20-minute Ted talk that explains the topic nicely, including how one method works.

Feats of memory anyone can do

And here are no less than three separate wikibooks that let you find out how many of the mnemonic methods work, and how you can use them.

##### Back to the question

It’s Monday, and I thought I’d recap what happened last week. (Who knows what you were up to this weekend.)

Here’s the link I added to episode 1’s show page, just because.

Comparison of the effects of unilateral and bilateral eye closure In cortical responses in kittens.

And here’s the link from Friday, as I talk more about synesthesia without bothering to explain what it is again.

What color is Tuesday?

Today we chat about synesthesia, wherein one sense can trigger another. Checkout the 4-minute video I found that tells you all about it.

Enough with plants and kittens, let’s move on to humans

## Enough with plants and kittens, let’s move on to humans

Plants grow differently in different gravity, and the brains of kittens develop differently when deprived of vision. So, what about those pesky humans?

Here’s an article from Scientific American about differences in the brains of those who lose their hearing or sight at an early age.
