Write a short essay on the various kinds of evidence for evolution

Fortunately it is as yet only through fantasy that we can see what the destruction of the scholarly and scientific disciplines would mean to mankingd. From history we can learn what their existence has meant. The sheer power of disciplined thought is revealed in practically all the great intellectual and technological advances which the human race has made The ability of the man of disciplined mind to direct this power effectively upon problems for which he has not specifically trained is proved by example without number. The real evidence for the value of liberal education lies in history and in the biographics of men who have met the valid criteria of greatness. These support overwhelmingly the claim of liberal education that it can equip a man with fundamental powers of decision and action, applicable not only to boy-girl relationship, to tinkering hobbies, or to choosing the familyy dentist, but to all the great and varied concerns of human life ------ not least, those that are unforeseen. According to the author, 'the great and varied concerns of human life' are about

It is possible to take a high quality photograph of a very fast moving object by illuminating the object for quite a small fraction of a second. You may have come across photographs of a bullet penetrating a banana or an apple in many text books or magazines. This is called 'stop action' photography because the fast moving object travels a very short distance during the time of illumination. Harold Edgerton, the inventor of stroboscope, was a pioneer of this kind of photography. A normal photographic plate works properly if it receives an energy of 4J during the exposure. To release this energy in a very small fraction of time, huge amount of power is required. Such huge power can not be generated directly from a battery because of its high internal resistance. To produce such power a capacitor is used. The time in which a capacitor discharges can be very short. Although, theoretically it would take a long time for a capacitor to discharge completely, it discharges almost completely in about 10 time constant. Consider the following situation A capacitor of 200muF storing 4J energy is made to discharge through a flash light in 2ms. This setup is used to take the picture of a bullet moving at a speed of 100m//s Assume that the flash light acts as a resistor and there is no other resistance in the circuit. What is the order of energy delivered to the flash light in 0.2 ms(approx).
