Experiment for Measuring Speed of light

The theory behind it is ...




Microwaves (and light) are energy waves. The waveform repeats along its length at intervals, each known as a cycle. The cycle has a wavelength. Each wave cycle has two points of high energy and two of low energy.

The points of high energy are where the margarine will melt first.

So measuring the average gap between the centres of adjacent patches gives us a distance that is half the wavelength.

The wavelength is a distance in metres, the length of one cycle.

The frequency is the number of those cycles per second.

Multiplying them together gives a figure that has units of metres per second. That means it is a measurement of speed.

Celebrating Travel

3 guys, 44 days, 11 countries, 18 flights, 38 thousand miles, an exploding volcano, 2 cameras and almost a terabyte of footage… all to turn 3 ambitious linear concepts based on movement, learning and food ….into 3 beautiful and hopefully compelling short films….. = a trip of a lifetime.

TED: Origin of Pleasure

A nice Poem by an African Kid

When I born, I Black,
When I grow up, I Black,
When I go in Sun, I Black,
When I scared, I Black,
When I sick, I Black,
And when I die, I still black..
And you White fella,
When you born, you Pink,
When you grow up, you White,
When you go in Sun, you Red,
When you cold, you Blue,
When you scared, you Yellow,
When you sick, you Green,
And when you die, you Gray..
And you calling me Colored ??

does wearing helmets while cycling helps ?
