Saving the Rainforest with Old Cell Phones

Rainforest Connection is saving the rainforest with something sitting in your desk drawer!
Rainforests have some of the most complicated soundscapes on the planet. In this dense noise of insectsprimatesbirds, and everything else that moves in the forest, how can you detect the sounds of illegal logging?
The old cell phone you have hanging around and collecting dust may have the answer.

So, how exactly does one go about saving the rainforest with old cell phones?

After a visit to the rainforests of Borneo, physicist and engineer Topher White was struck by the sounds of the forest. In particular, the noises he couldn’t hear.
While on a walk, White and others came across an illegal logger sawing down a tree just a few hundred meters away from a ranger station.
This incident set White thinking that perhaps the best way to save the Earth’s precious rainforest is to listen to its loggers and poachers. And the innovation he came up with uses old cell phones to do this!
To introduce us to the innovation he came up with, here is Topher White on the National Geographic Live stage. National Geographic is promoting some incredible things, so go check them out to see what they’ve been up to lately!

Arithmetic and geometric progressions

Download Arithmetic and geometric progressions PDF file. This unit introduces sequences and series, and gives some simple examples of each. It also explores particular types of sequence known as arithmetic progressions (APs) and geometric progressions (GPs), and the corresponding series. In order to master the techniques explained here it is vital that you undertake plenty of practice exercises so that they become second nature. After reading this text, and/or viewing the video tutorial on this topic, you should be able to: • recognise the difference between a sequence and a series; • recognise an arithmetic progression; • find the n-th term of an arithmetic progression; • find the sum of an arithmetic series; • recognise a geometric progression; • find the n-th term of a geometric progression; • find the sum of a geometric series; • find the sum to infinity of a geometric series with common ratio |r| < 1.

Factors to look after while using a cylinder gas

ere have been many cases of gas cylinder explosions and when this happens, lives are lost and properties worth millions are destroyed.
