Scientists Discover Material Harder Than Diamond

Currently, diamond is regarded to be the hardest known material in the world. But by considering large compressive pressures under indenters, scientists have calculated that a material called wurtzite boron nitride (w-BN) has a greater indentation strength than diamond. The scientists also calculated that another material, lonsdaleite (also called hexagonal diamond, since it’s made of carbon and is similar to diamond), is even stronger than w-BN and 58 percent stronger than diamond, setting a new record.

Diamond is still the hardest naturally occurring substance.

What answers to all these problems?

“Why water boils at a 100°C and methane at -161°C; why blood is red and grass is green; why diamond is hard and wax is soft; why graphite writes on paper and silk is strong; why glaciers flow and iron gets hard when you hammer it; how muscles contract; how sunlight makes plants grow and how living organisms have been able to evolve into ever complex forms – the answers to all these problems have come from structural analysis” - Max Ferdinand Perutz

It's about the history of mathematics in the 17th century in Europe.

One part of the programme is about Isaac Newton who is not only a physicist but also a mathematician. He is very famous in physics on his discovery of gravity and also a one of the most famous contributors in developing the calculus.

Eye Jewellery

The first new technique of Eye Jewellery was performed in The Netherlands in 2004. A tiny platinum jewel stud is inserted into the eyeball as shown in the picture below.

The latest Eye Jewellery Project was revealed in 2008. The project was designed by Eric Klarenbeek, an artist. This eye jewellery was displayed in an exhibition of jewellery influenced by the natural world, described as “a heady mix of taxidermy, genetic-engineered jewellery and natural pearls". The exhibition was hosted by The Wonder Room at Selfridges department store in London.

This is such a good programme of BBC. Wish Thai media would produce this kind of programme.
