Biography of a Mathematician: Sir Isaac Newton

This was huge in many ways as he proved definitively the heliocentric model first proposed by Copernicus.” (Universe Today) On top of all this he proved that all things in the universe revolve around the laws of motion. The laws of motion formed a footing for our understanding of the universe. This is a leap in science for his time and to this day. Newton’s gains in the field of mathematics we...

The Charge of the Light Brigade

In conclusion, Tennyson’s poem is such a powerful piece of writing because it takes a tragic story and turns it into a story of courage and heroism. What ignites so many emotions is that these soldiers sacrificed themselves because it was their duty. They obeyed the orders of their commander no matter the consequence. The last line of the poem sums up their heroism, “Honor the Light Brigade, n...

The White Tiger

Finally, the darkness and the light divide India in two very different categories, extreme poverty versus wealth, or “small bellies and big bellies” as Balram puts it. The contrast between the darkness and the light is so big that in the same country people can live in mansions with luxury cars and multiple servants while others can only afford a water buffalo in order to get nutrition to surv...

Emily Dickinson's "A Certain Slant of Light" Analysis Essay

“When it goes, ‘tis like the Distance, On the look of Death.” (15-16) Dead people have a distant look to them since the life in their being is gone somewhere else. We also see the exit of winter light at the end of the day in the same distant way we might see some deaths. Death is mysterious to those on earth, just as the sunset in the heart of winter is. The day is blanketed in shadows due ...

Friction Lab

the horizontal at which the block just breaks away. This is the limiting angle of repose θ max. Measure it with a protractor (see photo that follows for an alternate way of measuring the angle) and record the result. You may also want to measure the base and the height of the triangle formed by the board, the support, and the floor or table. The height divided by the length of the base equals the...

Beer’s Law Lab Report

Possible errors that may have occurred during this lab have to do with calibration of the spectrometer. The transmittance values changed second to second so if the timing was not perfect in measuring the samples, the transmittance would have been erroneous. The transmittances would have been too high (based on experimentation) so the absorbance rates would have been too low. This in turn would hav...

Bending of Beam Lab Report

6. Conclusion: As mentioned before, with this experiment we concluded that the deflection of a beam is different depending on its position. We also concluded that when the beam is positioned with its thin side on the supports it is able to carry more load than when it is positioned with its flat side on the supports. This is due to the fact the beam’s inertia change as the position changes. When...

Polarized light lab report

Throughout the experiment using the polarized filters it was clear that when rotating one the filters the image or region being looked at increased in brightness and then it became dark making it difficult to see through the filters. This was proven multiple times when looking at bright regions of the sky, and looking out the window of a car windshield that was reflecting sunlight. Problems were e...

Physics of Xray

The anode is positively charged which attracts the electrons to it. When the electrons are thrown from the cathode to the anode, they hit the target. The anode is angled which causes the target to have a larger area, therefore resulting in a smaller effective focal spot size. When the electrons that are thrown to the anode hit the target, they are redirected down to the patient, forming an image o...

Mathematics & Natural Sciences with absolute certainty (TOK)

It is not possible for humans to achieve absolute certainty in knowledge using mathematics and the natural sciences. Mathematics is a creation of man to organize and communicate highly complex concepts and theories to others through a kind of language which goes beyond the spoken or written word. Most people do believe the written word to be more true that the spoken word, as seen, this can be sho...

La Jument Lighthouse

These series of pictures taken by Jean Guichard inspired many places to take the safety of lighthouse keepers more seriously. The improved technology and increased mechanization have now made lighthouse keepers unnecessary. Today in the U.S. all of our lighthouses are automated except for one in Boston, which was the first one built on our shores. Many lighthouses are no longer needed because of a...

Marie Curie Short Biography

Marie actually had her prizes melted down to serve more “useful” purposes. In other selfless efforts, she gave away her Nobel Prize money and was a big help when World War 1 broke out. Pierre ended up dying in a traffic collision. Marie died years later of Leukemia, due to long-term exposure to radiation. This would have killed Pierre as well if he had not died by other means. Marie was 66 whe...

Lab report calibration of volumetric flask

Meanwhile, there are some possible errors occurred during the experiment, thus the result was distracted. In order to overcome the error, we have to make sure that the eye position is perpendicular to the reading scale of the apparatus to avoid parallax error. Last but not least, the beaker should be clean and dry properly so that there is no water left which can affect the mass of the next trial....

Teacher - Guiding Light

Later, God elevated him to the post of Cardinal in the Catholic Church. He is none other than Cardinal Richard James Cushing. The scripture tells us how Jesus Himself showed us the extent to which one should forgive. “Father, forgive them for they know not what they are doing.” (Luke 23:34).Are we able forgive the mistakes of our own students’?
