Crookes tube

Wilhelm Conrad Rontgen was born on March 27, 1845 in Lennep, Prussia; which is now Remscheid, Germany. His family moved to Apeldoorn in the Netherlands, where we went to Institute of Martinus Herman van Doorn, a boarding school. He did not show any special aptitude, but he had a fascination with nature and loved roaming the countryside and walking through forests. Later he attended a technical school in Utrecht, but unfortunately was unfairly expelled for allegedly drawing a rude caricature of one

Imagine a machine that made what was once invisible, visible. Wilhelm Roentgen discovered the X-ray in 1895. X-rays impacted the field of medicine greatly. The discovery of X-rays significantly changed how we could see the human body, treatment options, and how we viewed X-rays. Wilhelm C. Roentgen was a German physicist. He was born on March 27, 1845, and died on February 10, 1923. He was married to, Anna Bertha Ludwig. He received education from the University of Zurich, the Institute of Martinus

During the cold winter of 1895, a German scientist by the name of Wilhelm Conrad Roentgen was working with a cathode-ray tube when he noticed nearby crystals were glowing. When Roentgen reached for the crystals he was amazed when the shadow cast on the crystal was not of his whole hand, but just his bones. Roentgen covered the tube with heavy black paper and saw that the crystals still glowed and the shadow of his hand bones still shown through, he then determined that a new ray was being emitted

The science behind the x-ray goes back to a chemist called Sir William Crooks. He was born June 17th 1832 in England. Crooks developed the Crooks Tube in 1870. This was an important invention for scientists to come, among them was Wilhelm Roentgen who in 1895 was credited with the discovery the x-ray. Back when the x-ray technique was new, people didn’t realize the damage radiation could cause. This changed soon when it was discovered how people were severely injured from the exposure, as they were

atomic bombs; the people who chose to use the science in that manner are the ones responsible. 5. Who was Sir William Crookes and what did he contribute to the urgency of producing ammonia, NH3 from nitrogen in the air? Sir William Crookes became president of the British Academy of Sciences in 1898. Crookes invented the Crookes tube, a precursor to cathode ray tubes and he is credited with discovering the element thallium. When he was appointed president of the Academy, he gave a speech in

Observation: Last week, a ball dispenser was out for the children to play with. It was on the top of the shelf and “Child A” was trying to reach for it. “Do you want the ball dispenser ‘Child A’?”, I said. I took it from the shelf and put it on the floor; “Child A” sat down. I pressed the switch and the ball came out from the ball dispenser. He smiled and I said, “Oh! There it is!” as the ball rolled on the floor. He stood up walked towards the ball and picked it up. He walked back and put the ball

Hypothesis: We hypothesize that reagent Malonate will inhibit Succinate Dehydrogenase (SDH) activity. Background: Malonate, also known as propanedioate, is a classic example of a competitive inhibitor. Malonate has a molecular structure that is similar to succinate, so it has the ability to bind to the active site of succinate dehydrogenase and inhibit enzyme activity. However, malonate is sufficiently different from succinate that it cannot be dehydrogenated. [1] Malonate working as an inhibitor

Tube 1 and 2 contain functioning enzyme extract and substrate solution, ribose-5-phosphate. Furthermore, the conditions in tube 1 and 2 allow the reaction to proceed to form ribulose-5-phosphate and the mount of product formed can be measured. With tube 1 and 2 being identical, averaging the absorbance allowed minimizing the error due to differences in enzyme concentration and contaminants within experimental procedure. Tube 3 is used to boil the enzyme extract to investigate the relationship of

twelve test tubes total were used; four of them were the control tubes, which had no algae solution contents. The reason for not adding algae is that the control tubes solutions are meant to be the starting point for comparison that has to stay the same throughout the length of the experiment. They are used to set up the blanks on the spectrophotometer (instrument used to measure the amount of light at a specific wavelength) for each of the remaining eight tube solutions. Each time a tube is read by

Learning by observation is a type of learning in which an individual observes the behavior of others, sees the consequences of the behaviors, and then attempts to carry out the same behavior. Social learning is based on the standards of classical and operant conditioning and observational learning. It is a commonly shared belief that people have an instinctive ability to imitate the behavior of others. However, this ability is not unique to humans. Animals have also showed evidence of being able
