Observing With NASA: Remotely controlled telescopes which YOU can use!

There is no doubt that the sky is an amazing piece of art. When you look up at the sky in a clear and dark location, the sight of hundreds of stars can literally take one’s breath away. What’s amazing is that in the spaces between the stars and planets lurk more things than you can imagine – nebulae, galaxies, even more stars, and who knows what else which has yet to be discovered!

Have you ever wanted to use a telescope or take photos of celestial objects, but never had access to one? Find out more about Harvard’s Observing With Nasa (OWN), a website which allows you access to remotely controlled robotic telescopes, and see what kind of photos you can produce!

Do you wear a watch?

Sitting in a bus, or a train, or even walking about the streets is always a good opportunity to take a look at other people and to see if they are wearing a wrist watch. Ok, I don’t actually do that often, but it is always an interesting experiment to perform. I’ve recently heard arguments that [wrist] watches are no longer needed, that they are a thing of the past. People will now take a look at their phones to see what time it is, or glance at a clock on the wall. However, I think watches are still relevant in these modern days. Here’s why.

I can hear you…

Meet my one and only, ominous looking…

Sound Reflector
Sound reflector!

With this amazing piece of equipment, I can listen to your footsteps from across an entire field, I can eavesdrop on conversations, so you better not say anything bad about me! […]

Fourier Series – very basics

I don’t pretend to be an expert on Fourier Series, but I did find it interesting when just knowing the basics allowed me to prove an interesting statement. This is the 1st of 3 parts of the proof. It is therefore essential to know a few things about Fourier Series. This first part introduces the idea of fourier series.

My ‘Complex Argument’ to arguments of complex numbers

After some lengthy discussions on the solution to arg(z) = arg(z -1 + i) I decided to come up with a ‘simple’ explanation on how to get the answer. You decide whether it’s simple. I think it is. Here it is – The arguments of arguments.

Sorting algorithms

Given a set of let’s say, 20 numbers, and you’re asked to arrange them from the least to the greatest. Here is the “bubble sort” and “shuttle sort”, two algorithms which will arrange them in order. Needless to say, you should not need to use them, but they can be interesting.

[EDIT : Ooh, discovered that the site layout breaks in IE because of some silly bug when viewing this post. Sorted that now. Phew. Irritating IE]


Testing MathML on the site. Hopefully it works.


First of all.. thanks all of you guys who contributed to that card… thanks a lot… It was really nice.. and I guess… the most thanks to my family! I’ve just finished reading ‘Flatland’ by Edwin Abbott… if you want to read it, go to THIS LINK It’s quite an interesting story of the land […]
