Friday, December 31, 2010. When a combination of neutrons and protons, which does not already exist in nature, is produced artificially, the atom will be unstable and is called a radioactive isotope or radioisotope. There are also a number of unstable natural isotopes arising from the decay of primordial uranium and thorium. Overall there are some 1800 radioisotopes. At present there are up to 200 radioisotopes used on a regular basis, and most must be produced artificially. Isotopes used in Medicine.

Wednesday, March 13, 2013. The central core of an atom. Entire mass of an atom is concentrated in the nucleus. The atomic nucleus was discovered in 1911 by Rutherford. Nucleus consists of protons and neutrons and in general protons and neutrons are called nucleons. Hydrogen nucleus does not contain neutron and has only one proton. The rest mass of proton is 1.007277 amu and charge of proton is 1.6 x 10. Coulomb. The rest mass of proton is 1836 times the rest mass of electron. Representation of a nucleus:.

Monday, December 12, 2011. Neutrinos come in three types, according to the standard model of particle physics: the electron neutrino, muon neutrino, and tau neutrino, which have all been confirmed experimentally. A fourth, ‘sterile’ type has been proposed, which is immune to the weak force of the standard model. Were sterile neutrinos to be found, a new realm of physics beyond the standard model would open up. Posted by Dr.K.Ilangovan. Physics in Tamil literature. Thirumoolar, Eight Century A.D. MJP PUBL...

Saturday, March 12, 2011. A poem from Manusyaputhran. நாம் ஏன் இப்படி. இருக்கிறோம். சதா முணுமுணுத்துக்கொண்டு. எப்போதும் துணிகளை மடித்துக்கொண்டு. எதையாவது சுத்தம் செய்துகொண்டு. யாரையாவது சபித்துக்கொண்டு. எதையாவது அடைய முயற்சித்துக்கொண்டு. எதனிடமாவது தோல்வியடைந்துகொண்டு. எப்போதும் நம்மை நிரூபித்துக்கொண்டு. ஒரு சிகரெட்டைப்போல எரிந்துகொண்டு. தேவையற்ற பொருட்களால் நம் தனிமையை நிரப்பிக்கொண்டு. நம் குழந்தைகளை சந்தேகித்துக்கொண்டு. எதையாவது தேடிக்கொண்டு. தவறிப்போன சந்தர்ப்பங...யாருடைய அனĮ...கடன் க...
