Wolfram Alpha shows us how a dog sees Obama

Wolfram Alpha is an amazing knowledge engine that can answer questions we can't even imagine. Today I bring you one such case. Would you imaging Wolfram Alpha to be capable of showing us how a dog sees Obama? Well... it may sound like an April's foll prank, but it actually can.

You can check it out for yourself, by asking Wolfram Alpha: apply dog vision to image of obama.

This system assumes the result based on two color photo-receptors on dog's eyes, and 20% of human visual acuity, and it gives us an estimate of how our trusted companions see us.


Next I tried doing the same for cats, but it seems Wolfram is more of a dog-person, as the same query for cats didn't provide any results. You can try other images besides Obama though, I'll leave that for you to explore.

More stuff you can do with Wolfram Alpha? How about...

• What's on the other side of the world
• What's the lifespan of different animals
• How many bills you'd need to cover a country

Amazing stuff... isn't it?

Wolfram Alpha

I don't know exactly when Wolfram Alpha redesigned its homepage - but what matters the most is that its know a lot easier for newcomers to find out a lot more about this "computational knowledge engine".

Most people won't easily grasp what Wolfram Alpha is... and it isn't easy remembering examples to showcase its potential. But know, you can do it with just a few simple clicks. The Wolfram Alpha main page is now full of small icons - icons that you could be fooled into thinking were just part of the background wallpaper, but that spring to life when you move your mouse over them. In there you'll find examples in countless areas: arts, space, biology, architecture, physics, geography, mathematics, music, time, money, etc.

So... just start clicking away, and see the kind of stuff Wolfram Alpha can help you with.
