Why Evolution is True is a blog written by Jerry Coyne, centered on evolution and biology but also dealing with diverse topics like politics, culture, and cats.

This video from the excellent Numberphile YouTube channel shows a very simple game that has the most unexpected outcome. My only criticism of this video is that I’d like to be shown the explanation, even if it’s complicated! Maybe readers can help me.
I don’t think I’ve ever played a video game in my life. I won’t give my reasons as I don’t want to offend readers who like them and would disagree with me. To each their own!
But this is one game I really would play: it’s called “HK”, and is in development; in fact, they just got funding. It’s about the stray cats of Hong Kong, and I love the graphics. I don’t even know what the game is really about! I do know it’ll be a while, since the developers are two guys and (they say) their cat. There’s a bit of information here:
But this game is about more than just being a cat. This is about being a cat in Hong Kong. More specifically it’s about being a cat in Kowloon Walled City, a crazily populated area of Hong Kong that is pretty much ungoverned. That’s just an astonishingly interesting high concept for a video game.
Watch their Twitter page and Facebook page for further developments:

There are more graphics on the “devblog“,
When I was younger, I would invent a game for myself involving a time machine. The rules were these: you were given a time machine, and you could set it to go back to just a single place and time in the history of the Earth, and stay there for 24 hours. You would then be returned to the present. You would be allowed one notebook and pencils, but no cameras, video or otherwise, or recording devices.
And you could do this for two reasons: to answer as many scientific questions as you could by being in one place and time (you were allowed to bring your notebook back), or to simply satisfy your own curiosity.
There was one more provision: you could also specify to be set down in a single area where there were specific things you wanted to see, like a band of Neanderthals or a T. rex, for of course you wouldn’t know where or when you could see them in advance.
I never resolved this question for myself, even to the extent of seeing whether I wanted to answer scientific questions or just see what a T. rex really looked like.
I’m asking readers here (and I hope I’ve been sufficiently specific) this question: where would you want to be taken for 24 hours in your time machine? Please state your reasons, too.
For reasons I don’t understand, many secularists and atheists are also gamers. While I can appreciate their enthusiasm, I don’t really share it, as I’d rather read a book or go to a good movie than play a video game. However, here’s an exception that I enjoyed for about 15 minutes.
It’s called Chat Noir (black cat), and your object is to trap the cat before it leaves the playing field. Try to encircle the cat with dark green dots (click on them with your mouse or its equivalent, one at a time) before it can escape to an outer dot.
Click on the screenshot below to begin. I never even came close to winning. The cat is too damn wily! After you’ve lost, press “reset” at the bottom to have another go.
Diane G. (who has succeeded), sent me a screenshot of two of her successes. There are two ways to win, she says. The first is to simply trap the cat by blocking out the outer circles (once the cat gets on an outer dot, you’ve lost):
The other way is simply via fusillade: blocking the cat by completely encircling it with black dots. You have to be quick on the mouse for this oneL
Did anyone win?
I got an email from one Lin Taylor, who pointed me to a swell new quiz that she and a biology friend constructed. I’m not much for games, but this is a good one, because it not only challenges your knowledge of biology but it’s educational in several ways. Here’s her email and the link:
I’m a biologist turned programmer (I took one of Matthew Cobb’s zoology classes at university!) and long-time reader of your blog. A few weeks ago you published a post ‘how many of these weird animals do you know?’:
My friend and I were disappointed that this wasn’t an *actual* quiz, with multiple choice options… so being industrious people, we made one of our own:
It’s populated with 500 species from the Encyclopedia of Life database, so there is a pretty healthy variety of animals and plants in there (I haven’t seen any fungi or slime moulds yet, unfortunately…). We thought you might enjoy playing it.
I did enjoy playing it, and hope you will too. Again, it’s here, and here’s how it works. For any round you can choose between 3 and 5 questions, all at either “easy”, “medium,” or “hard.” With the first two you can have hints (unlimited for “easy”); but no hints for hard.
Your job is to guess the Latin binomial of a pictured species given three choices. For example, below is a “hard” one (not hard for me, as you see, because I recognize the Latin names of all felids!). And this one is easier than most hard ones.
After each game you can play again, and will get new animals. Try it!
(Lin warns me that if too many people play the game, it could overwhelm the server.)
[JAC note: Matthew told me he’d written this draft post and that I could put it up or not depending on whether I liked it. I decided to post it without seeing it, just for the surprise. I predict that the balls will all end up at the bottom, but hat do I know?]

… you tipped a load of plastic balls onto the bottom of an up escalator. Where would they end up? We’re talking lots and lots of balls. Make your prediction and then click on the video. (And yes, I know the people making the video cheat.) This was posted about 30 months ago – the people who made it (Ian McCart) had a website that no longer works. I think it’s some kind of kinetic artwork.

We all know about this one, and I bet some of you are experts. (I am lousy at stuff like this and never solved my only cube.) Today’s Google Doodle celebrates the 40th anniversary of the famous cube invented by Hungarian Erno Rubik, whose name will linger in history longer than any of ours. If you go to the page, and I guess you’d better go soon, you’ll see this, and it will whirl around when you click on it. When it gets big, you can go ahead and solve it. The first reader who does, and sends me a photo, will be honored on this post. (Sorry, no free books or mugs today.)
As Forbes notes:
According to Wired, Google was finally able to create their most sophisticated Doodle yet thanks to the widespread adoption of CSS 3-D Transforms on most web browsers.
“CSS 3-D Transforms lets us display the cube in a 3-D space, as opposed to having a sort of rasterized 2-D experience,” lead engineer Kristopher Hom told the publication. “It makes it feel alive, because as you’re moving your mouse, you can see the cube rotating in 3-D space.”
Here’s a screenshot of what you’ll see, but click here to solve the puzzle—if you can:
A few more salient facts:
[The invention] was in 1974, in Soviet-controlled Hungary. The architect eventually managed to license the cube to Ideal Toy Corp in 1980. It was originally called the Magic Cube, but was rebranded with the more memorable name we have now.
Since then it’s sold over 350 million units, making it the best-selling toy ever, though it’s not as popular as it once was. The world record for solving the Rubik’s Cube is held by Mats Valk, a Dutch teenager who managed to complete the cube in just 5.55 seconds.
The LEGO Mindstorms-built Cubestormer III robot—powered by a Galaxy S4 smartphone—solved the cube in just 3.25 seconds.

UPDATE: Reader Alan R. (see below) solved it; the proof and time taken are below. If you can best it, send me proof.
Reader Joseph G. sent me a better time this a.m.:
