NEW SCIENTIST magazine has organised a Science Exhibition in London Excel center for four days from september 20, 2018. I visited the exhibition on second day. There was a big and enthusiastic crowd mostly students with their teachers or parents.

Over 100 stalls were there from University departments, government departments, book publishers and private business selling from meteorites to robotic toys. Some of the talks were well attended.

As soon as I entered the site I saw the big stall by European Space Agency. They displayed the models of their future space probes.

What surprised me was a person buying two meteorites for 140 pounds. Such stones from space are available in plenty in India but without any scientific details. Meteorite business is a big business here. The stones that fell from the sky are scientifically analysed, recorded and documented. From tiny samples to big stones are displayed in two or three stalls. Two authors were selling their science books personally signing the copies. Freebies such as brain caps were given to school students in some stalls.


140 speakers are lined up for four day talks.


All of us emit radiation to some extent. Even bananas emit radiation. But all of us know the radiation from nuclear materials are harmful. Even smoke alarms at homes have radiation. A stall explained all these things and allowed us to measure the radiation from different objects. It was interesting and educating.


Geology stall explained all about earth quakes and the man warned me that India is due for a big earth quake (not political!) in the Himalayan range, so do California. But no one could predict or forecast when it is going to happen. Ganges, Sarasvati and other rivers changed their course during such past big earth quakes.


Most interesting was a robot which laughs when you tickle it in its head or cheeks.


Harvard Univesity Press displayed their latest science books. New Scientist is selling their books and magazine at a discounted price. I have taken some pictures which would explain more than words.
