When deciding whether or not mistakes are a part to making discoveries‚ the sides are pretty evened out. But with this essay‚ the siding is that mistakes are a key part to making discoveries. Let’s get into it. First off‚ we have an example of the argument. In the article Lost Cities‚ Lost Treasures‚ there is a scholar and businessman known as Heinrich Schliemann. Heinrich is searching for the lost city of Troy. He comes upon a man who owns a presumed site‚ named Frank Calvert‚ who is modest and

Nothing could deter him from the path that he had chosen for himself. Mr. and Madam Curie could discover Radium- a great boon to humanity-only because they were persons of will‚ prepared to lay down even their lives in the pursuit of their ideal.

Not long after checking in‚ the specialists do a number of tests including the use of radium and additionally cutting two little bits of tissue from Henrietta’s cervix. Her cervix was going to get cut without her being educated all together for the specialists to have a few samples. One of the samples was sound tissue while the other was

Unlike something ever seen before‚ Henrietta’s cells were placed into a petri dish to see if they would grow‚ and they did. As a matter of fact they have yet to stop growing. Some would call it a medical miracle‚ and those that discovered it “Heroes of Modern Medicine”. Many would argue that scientists had the right to take Henrietta’s samples‚ after all Henrietta signed “a form”. Many would justify the doctor’s actions and overlook misconduct or abuse of power as they neglected to inform Henrietta

Facts of the periodic table While Dmitri Mendeleev is most often cited as the inventor of the modern periodic table‚ his table was just the first to gain scientific credibility‚ and not the first table that organized the elements according to periodic properties. There are 90 elements on the periodic table that occur in nature. All of the other elements are strictly man-made. Technetium was the first element to be made artificially.

Carcinogens and toxins such as lead‚ uranium‚ mercury‚ ethylene glycol‚ radium‚ methanol‚ hydrochloric acid‚ and formaldehyde are used.

Howard Jones was the first gynecologist to look at and biopsy Henrietta’s cervical tumor. Jones believed that radium would be the best form of treatment for Henrietta’s cancer as opposed to surgery. Richard TeLinde was an expert on cervical cancer for his time. He believed that cervical cancers were all carcinoma in situ before they became invasive carcinomas
