Brand new idea, Not a new invention?!

The lightbulb, The most widely known source of light, excluding the sun. It has been around for a couple hundred years, with several different versions. The ordinary lightbulb, biodegradable, power saving, etc. However, who invented the first lightbulb? You would say Thomas Edison, but did you know that that is false? He didn’t invent it, he recreated it for a more conventional use. So before Edison began working on the lightbulb, it had already been around for a long time

You see, as Edison started to “invent” the lightbulb, Joseph Swan had already created a platinum rod lightbulb. By the time Edison finished his creation, He and Swan had submitted their versions at the same time. Instead of filing for a lawsuit, Edison and Swan agreed to split the credit between the two of them, but why does Edison get all the credit? Well, because his was more conventional. It would burn for up to 600 hours before burning out. Using carbon and bamboo filaments, instead of platinum rods and coils, made the lightbulb more conventional.

This part will explain the difference between the two creations, if you don’t like math and a little bit of science, go ahead and skip this. So, with Edison’s lightbulb being able to burn for 600 hours, and the specific heat capacity of his filaments were 150 degrees Celsius, and their mass was 0.0176 grams. With the formula q=mCt, we can say that his lightbulb would be at 1584 degrees Celsius, which is the burnout temperature. Now using the same formula, q=mCt, and q=1584, the mass of Swan’s platinum rods were.00896 grams, and the heat capacity is 1768 degrees Celsius, We can estimate that it would only last 100 hours before a burnout.

Now taking a step away from the math and science, Edison did not invent the lightbulb, he in fact hired professionals from various universities, Princeton for example, to make a more reliable, affordable, and efficient lightbulb compared to Swan.

Facts of Graduating, there is only the 33%.

Grab your cap and gowns, and throw them away, because only 33% of you will graduate in 6 years. Reality has just kicked in. The chances have slowly dimmed over the years due to multiple factors. A major role that is a common problem in this generation, though it does not effect everyone, is that the increase in technology and distractions are rising to a maximum. An increase of distractions in the way of social media, video games, etc. is causing people to lose focus. This loss of focus can result in an overwhelming amount of failure of assignments. Believe me, I’ve been there. Due to a study in multiple colleges by Lynn O’Shaughnessy, a calculation was determined and dropped some hopes and dreams of college students. Other than distractions and technology interferences, there are factors such as transportation that is unavailable, Unable to pay, and so on. The list of excuses, but not all are excuses, continues, And it’s turning into the next, “My dog ate my homework”. It’s now I di

Impeached, or in a peach?

Image
The real thing about impeachment, is not the removal from office or a position, but rather a criminal charge of those in power. The main purpose, or a reason for impeachment is due to unlawful acts. For example in this year, President Trump is being impeached for bombing Qassem Solemani. Trump, however, is not the first to be impeached, but rather the third. The first impeachment was against Andrew Johnson, due to the violation of the Tenure of Office Act. The act states that it is unlawful of the president to remove office-holders without approval of the Senate. Even through the presidential veto, the Act was still passed.  After the Senate had found out that Johnson had removed Edward M. Stanton, U.S Secretary of War, they had filed for an impeachment of Johnson to the House of Representatives. In order for Johnson to be removed, The House needed a three-fourths vote from Parliament. This was not achieved, since the Senate voted 35 to 19, 1 vote short of his removal. And
