Amazing Facts about Sex.

Did You Know…..

      I.            The average male produces several million new sperm daily, while a female produce no more than that throughout her lifetime. A man will ejaculate about 1 to 2 trillion sperm in his lifetime.

 II.            Unlike other cells, which contain an individual's full DNA, the egg of female and sperm of male each contain only half of the DNA required to reproduce a new human. A single cell contains 6 billion steps of DNA.

III.            Use of the condom was first noted in published literature in the early 1500A.D. It was originally made of linen, and historians believe the legendary lover Casanova used linen condoms. The first legalized condoms in the US were made from vulcanized rubber in the 1870A.D. They were expensive and annoyingly thick and meant to be reused. Today, Japan leads the world in condom use.

Earlier science and spirituality used to be considered as two opposite parts of life. Belief in one meant disbelief in another but time went on and the terms have been expressed together. Today science defines spiritualism and vice versa.

After the World War II, industrial revolution began. Europe and America proved themselves a step ahead than the rest part of the globe.

Nobel Prize in Physics 2010 for Graphene -- 'Two-Dimensional' Material

The Royal Swedish Academy of Sciences has awarded the Nobel Prize in Physics for 2010 to Andre Geim and Konstantin Novoselov, both of the University of Manchester, "for groundbreaking experiments regarding the two-dimensional material graphene."



 Konstantin Novoselov and Andre Geim



A thin flake of ordinary carbon, just one atom thick, lies behind this year's Nobel Prize in Physics. Geim and Novoselov have shown that carbon in such a flat form has exceptional properties that originate from the remarkable world of quantum physics.

Global warming refers to the rising global temperature. It causes climate change that is responsible for: flood; frequent and intense rain and snow; change in the normal occurrence of monsoon thereby affecting crop production; drought; land slide; vector borne diseases; more frequent tropical storms; forest fire and extinction of species due to the loss of ecological niches.

          Scientists all over the world believe that global warming is caused mainly by two processes as given below:

1) Increase in the level of green house gases such as carbon dioxide (Co₂), chlorofluorocarbons (CFCS), methane and water vapour due to burning of fossil fuel and deforestation.

2) Milankovitch cycle
