Calculator Contest and Monday Math Madness

March 27, 2009

Firstly, there is a contets for a calculator called Nspire. If you want to get one free, you should enter. I want one too, so I too will participate. ^_^ Secondly, the blog has Monday Math Madness, which is basically a biweekly (or something like that) feature of interesting math problems. Check out number 28!


Trailer for Eureka 7 Movie!

March 27, 2009

Yay! It is finally here. ^_^ A few months ago, I watched all 50 episodes in three days, and I liked it a lot. My favorite thing about it was the smooth and detailed animation. They didn’t use the generic striped line backgrounds. Nor did they use the exaggerated facial expression characteristic of anime, and the ones they used are rare. You can see why I am glad they are making a movie. Whether it is going to be good, well, I don’t know, but I did feel kind of nervous about it. So, here is the trailer:

If curious about what the show is about, watch a few episodes:

No MIT for Me

March 14, 2009

Oh well. 😦 I think I will go to a corner and indulge myself in self pity, denying  this ever happened, then blaming my brother while at it, and finally rebound in a manic state in which I am constantly feeding on chocolate and annoying everyone in my vicinity.


Spilhaus Clock

March 14, 2009

My astro club meeting was around a month ago, but still, I wanted to show you something cool. It is called a Spilhaus clock. It shows everything! It was made by a man named Athelstan Spilhaus. He is an oceanographer, geophysicist, and an inventor of sorts.

Here is how it looks like:

The clock has the following features:

1. The horizon and the Visible Heavens 
2. Sun Position in the Sky. 
3. Moon’s Position 
4. Position of the Stars 
5. Relative Position of Sun, Moon and Stars 
6. Day of Month and Year … a Perpetual Calendar 
7. Solar Time of Sun, Moon and Stars at Meridian 
8. Sidereal or Star Time. *
9. Current Phase of the Moon 
10. Time of Daily Sunrise and Sunset 
11. Mean Time of Moon Rise and Moon Set 
12. Mean Time of Star Rise and Star Set 
13. Current Time High or Low Tide 
14. Current Stage of the Tide 
15. Mean Solar Time** This clock is in

This one shows regular time.

Finally, this one shows the various times in various time zones.

Cool, eh?

*Solar time is the time it takes for the sun to be in the same position in the sky, exactly 24 hours.

**Sidereal time is the time it takes for the stars in the sky to return to the same position in the sky, which is 23 hours, 56 minutes. Yes, that is right, solar and sidereal time are different. In fact, the sidereal time is more of a “real time” because that is when Earth turns exactly 180 degrees, while in solar time, to keep up to the sun, the Earth has to turn a few degrees more.

Note how position 2 is when the Earth turns exactly 180 degrees in the orbit from position 1 to 2. Say in part number one, you are in a sunrise, then in part two, it still hasn’t risen yet because the Earth has to turn a bit more (part 3) so that the sun rises to the exact place as it was in position 1. See? Not that hard. ^_^ Unless I suck explaining things. So yes, if you have a question, you can comment on it.


It’s Pi Day!!!
