PHYSICS OF THE PAST One hundred years ago‚ in a poky apartment in Bern‚ Switzerland‚ Albert Einstein‚ then just a 26-year-old patent office clerk still working part-time towards his PhD‚ published five ground breaking scientific papers. Each of these papers‚ written during Einstein’s annus mirabilis ‚ has become a "classic" in the history of science: On a Heuristic Viewpoint Concerning the Production and Transformation of Light ‚ which discusses optical photons and photoelectric effects.

Effect of Temperature on Cricket Respiration Crickets are ectotherms that rely on their environment as a source of heat for their metabolism. Warmer temperatures allow crickets to respire at a greater rate.

The problem that we are solving is “How does the temperature outside affect the speed and heart rate of the runner?” We chose this to investigate “How does the temperature outside affect the speed and heart rate of the runner?” because we both play sports that require lots of running (Track and Field and Soccer.) Therefore‚ when running track outdoors the weather at the beginning of the meet may be colder‚ than the end when it’s most likely hotter. As well as a soccer tournament‚ you may play a tournament

process can be affected by several variables; one of the most notable variables is the temperature of the plant’s environment. Previous study has led me to conclude that when the temperature of the plants’ environment is low‚ the rate of photosynthesis is also low because the enzymes responsible for photosynthesis are not able to absorb as much heat energy and in turn will move slower. In contrast‚ if the temperature of the plant’s environment increases‚ the rate of photosynthesis will also increase

’Stock Records Accuracy’ means: (1) a correspondence between what is present on the computer file and what physically exists‚ in reality‚ (2) that activities which have been recorded as taking place against stock are truly what in fact occurred‚ and (3) that no activity which took place is unrecorded in the system. As we shall see‚ the central stock file is a most important element of any system within the company. The records within the file are ’keyed’ on each product’s unique item code**. That

Leaving The Past Happiness is something that everyone strives to create and continue to push for. But happiness is not that simple and can not be created by something. people have to accept life for what it is and not try to make up for the past‚ people should not try to create happiness like Granny weatherall a woman who attempted so many times to create her own happiness and feel better after being left at the alter. People need to accept their past‚ live on and know that they have accepted

2. How is the colour related to surface temperature of the star? The correlation between the surface temperature of a star and its colour is due to the phenomena known as black body radiation .A star is a black body‚where it aborbs all the radiation falling upon it.AS its temperatures gets hotter thanits surrounding‚the star radiates its on electromagnetic radiation‚known as black body radiation. This radiation is distributed unevenly but contionously through multiple wavelengths of the electromagnetic

The Aim of this practical was to observe what effect temperature had on the permeability of the cell membrane. Introduction Located within the vacuole of beetroot cells is a red pigment call Betalains. Typically these pigments are contained within the cell vacuole by the tonoplast (vacuole membrane)‚ however When beetroot is heated these red pigments escape the vacuole. This experiment aims to explore the effect of temperature on the permeability of the cell membranes (i.e. Tonoplast)

An understanding of the past is necessary for solving the problems of the present. However uncertain it may be that the past can be relied upon to solve problems of the present‚ a knowledge and experience of the past is instrumental in teaching conduct‚ morals and values in a world that is in dire need of insight and direction. 1. George Santayana stated ‘Those who cannot learn from the lessons of the past are condemned to repeat its mistakes’ a) Nations have now learned from the wrongdoings of
