Time Crystals

I read about a “crazy” theory the other day, related to perpetual motion. As the article says, Frank Wilczek has developed a proof of time crystals, physical structures that move in a repeating pattern, like minute hands rounding clocks, without expending energy or ever winding down. Unlike clocks or any other known objects, time crystals derive their movement not from stored energy but from a break in the symmetry of time, enabling a special form of perpetual motion.

Math does NOT suck

Math is cool
Math Art

I’ve always liked math, it gave me a sense of wonderment, a weird sense of discovery and a longing to dig deeper to learn more. It’s an endless subject with so many real-life applications. We wouldn’t have any of the technology we have today without math. Yet, people seem to hate it at school and try to avoid it at all costs when studying or working. But it’s not a hard subject. It just needs some background. Lose that and you are lost. You can’t go anywhere. It makes you think math is hard, or even worse, that you are too stupid to understand it. I loved it at school and university and yet I did not always understand everything. It took hard work but what I came to realize is once you get it, this is it. You can solve everything they can throw at you. Until the next chapter comes on. And the fun begins again. This post http://www.thebestpageintheuniverse.net/c.cgi?u=math reminded me of these things. Just wanted to share with the world.

By the way, the views on that post about cooking are spot on! What do you mean you can’t cook? Seriously? There are so many recipes out there and all you need to do is follow the steps. Like throwing some chicken into the pan. What’s so hard about that? Really! I cook every day and I never even thought it was about special skills. Just following steps and eventually some experience helps turn a simple dish into something yummy. Try this for inspiration http://foodgawker.com/

Oops, have I turned a math post into food again? Time to eat… now what shall we cook tonight? 🙂

2012, a year like any other?

They said the world would end on 21 December 2012; it’s everywhere: books, movies, TV, websites. Where does it come from? What does it mean? And as a popular TV show would put it: “Is it real?”

2012
End of the world?

NASA put together a really nice FAQ, pretty much dismissing all doomsday theories: http://www.nasa.gov/topics/earth/features/2012.html. I find the whole thing fascinating but I don’t think we are in any real danger, or have any sort of destiny coming for us this year.

A nice video on this:

Wishing you all a happy 2012 🙂

Which Subatomic Particle Are You?

I discovered a blog about science. It’s pretty cool, read it here (called Schrödinger’s Kitten believe it or not).

Other than being really really cool and keeping me occupied for many hours and days, it features THE ultimate personality test: “Which Subatomic Particle Are You?”

Take it here.

My results:
Muon — 57%
Quark — 28%
Neutrino — 14%

So what does that mean? Let’s take Muon, the biggest part of my personality:

From a middle class family, with a sensible, short name, you’ve made a career out of being an outsider — too light to be a hadron, too bent to be an electron.

Adopting a rock star lifestyle once you got the momentum to leave the unfashionable galactic suburbs where you grew up, you believe in living fast and dying young. The only reason we witness you at all is your relativistic effects pedals and a giant marketing machine passing on your hype quicker than you can travel yourself. You’re particularly popular among particle physicists, who have photos of you all over their walls.

Hate to be the one to tell you this, but your two-piece (‘muonium’? gotta love that modesty) is pretty generic. Sounds a lot like traditional lightweight duos.

Pretty accurate, don’t you think?

Life before Google

Life before Google

I found this picture and tried to remember what it was like not being able to “look something up”. I can’t really remember, I just remember how it became easier and easier to find things out, recall who the actor in that movie was, finding out the author of a book, looking up the correct spelling of a word and so on…

Information is taken for granted these days but we need to be careful; relying too much on digital media could backfire… I have heard of people who store their pictures on facebook and nowhere else. What happens if facebook decides to go offline… for good? What about wikipedia? Or google?  Or even worse, what if governments do decide we have too much freedom online and implement the infamous kill switch?

Just a thought…
