LIFE AND NON-LIFE





  Take a piece of salt harvested from ocean.  It  basically has cubical shape.  It is made up of sodium chloride molecules(NaCl).  The sodium and chlorine atoms are joined by ionic bond.  They are alternately arranged in rows, into planes and take the shape of cube.  We know sodium and chlorine are atoms that are made up of protons, neutrons and electrons.  Now they say, protons and neutrons are built from the particles called quarks.  

      Hence all non-life matters are made from fundamental particles like electron, proton etc,.  The particles constitute themselves into atoms.  Atoms are binded together to form molecules.  Molecules arranged themselves into some shapes or go shapeless like liquid and gas.  

      Life starts from non-life.  The atoms of some elements particularly carbon and hydrogen form complicated molecules.  The different set of molecules make plant or animal cells.  Collections of cells make tissues.  Then organs are constructed from cells and tissues.  The organs are made into life forms according to the blue print stored in their DNA.  The main organ brain activates, controls and monitors the life form(men and animals) by sending signals to other organs.  The life is born, lives, grows, multiplies and dies.  Once again it becomes non-life.

      Virus stays in the border between life and non-life.  When it is dead, it is like a salt particles.  But, if we put it in the water, it springs to life, multiplies and infects the host life.  Virus is a natural enigma.  

      Long dead animals and plants becomes stones(fossils).  It is reported that humans had turned 'stone like' due to volcanic eruption.  

 I want to end this piece by couple of lines from a poem.

  A river says:
"Men (life) may come , 
   men may go,
   but I (non-life) will go on for ever".

 Science update:  Stephen hawking plans a space voyage on Branson's virgin galactic.

LISSAJOUS FIGURES

  Definition:  "When a particle is subjected to two sine wave motion or two oscillatory motion at right angles, the particle describes lissajous figures".      We know sine wave motion and circular motion is basically same.  Hence we draw two circles A and B perpendicular to each other.  The circle B rotates twice faster than circle A.  That is, frequency of circle B is two times than that of A.        A particle at the intersection of two circles is subjected to two sine wave motion   A and B at 90 degree simultaneously.  The particle will describe figures depending on the frequency and phase of A and B .  In our case, the ratio of frequency is  1:2 and the two waves are in phase.        To draw lissajous figures :  A moving point in both the circles are chosen.   Here we should remember; during the time taken by the circle A to complete one rotation, circle B completes two.  Hence the points are marked on the circles according to their speed.  Then straight lines

THE PARABOLA

          A jet of water shooting from a hose pipe will follow a parabolic path.  What is the so special about parabola.    Y= x^2 Draw a graph for the above equation.  It will result in a parabola.  This parabola is also called unit parabola.  Any equation involving square will yield a parabola. Example:  Y = 2x^2 +3x+3 (also called quadratic equation)    X= 2 and -2, both  satisfies the equation 4 = X^2.  Parabolic equations always have two solutions.     Any motion taking place freely under gravity follows parabolic path. Examples:   An object dropped from a moving train,   A bomb dropped from flying plane,  A ball kicked upwards.      If a beam of light rays fall on the parabolic shaped mirror, they will be reflected and brought to focus on a point.  This fact is made use of in Dish Antenna, Telescope mirrors, etc.      Inverted parabola shape is used in the construction of buildings and bridges.  Because the shape is able to bear more weight.      A plane

CASINO'S GAME

           Let us find out how the casino survives with mathematics.      Say, your friend invite you for a game of dice.  You must bet (wager) 2 dollars.  If you roll 'six' you will get back 8 dollars.  The game will go on for 30 rounds.  All sounds good.      The probability of rolling 'six' is 1/6.  Since the game will be played for 30 times, the 'expected win' is 30*1/6 = 5.  That is, you are expected to win 5 rounds out of 30.  Hence your gain will be 5 * 8 =40 dollars.  ok.  This also implies that you will loose 25 rounds.  Hence your loss will be 25*2 =50 dollars.  Your net gain will be gain-less = 40-50 = -10 dollars. For 30 rounds, the loss is -10 dollars, Hence, for one round =-10/30 = -1/3 dollars.  There will be a loss of -1/3 or 0.33 dollars per round.  It is not a fair game.     Let us make a simple formula to calculate  'Pay out per round\. The probability for a win = p The pay-out in case of win = V No. of rounds = n The expect
