“Steel plates are commonly attached to each other with rivets, which are slipped into holes in the plates and rounded over with hammers. The hotness of the rivets makes them easier to round over, but their hotness has another important advantage in providing a tight fit. What is it? Explain why.” This relates to one of the characteristics of heat, in that heated objects expand, then contract when the temperature decreases, since the molecules move faster in heat and slow in the cold. The hot…

No one would have believed, in the last years of the 19th century, that physics was heading for a crisis. It seemed like all the large questions had been answered. The behaviour of bodies, from asteroids to galaxies, was predicted by Sir Isaac Newton 's laws of gravity and motion. Magnetism, electricity and light were linked by James Clerk Maxwell’s Equations. The understanding of the atom had reached the plum pudding stage, where an atom was a globe of 'stuff ' with the positive and negative…

4. Why PdO/TiON NP powders are chosen as photocatalyst? There are many reasons why PdO/TiON NP powders are chosen as a photocatalyst for MTBE mineralization under visible light. These reasons are listed and discussed as follows: 1- The synergistic effect. 2- The ease of synthesis. 3- The memory effect. 4.1 The synergistic effect Nowadays, modified TiO2 by metal and nitrogen is considered as one of the most promising TiO2 based materials for photocatalytic applications, which is able to…

“Never give up on what you really want to do. The person with big dreams is more powerful than one with all the facts.” Albert Einstein, a specialist on developing general theories and determined scientist. This quote connects to a time in my life when I was eight years old and I found something that I really loved. But it appeared extremely hard. It was to become an artist and I had big dreams of becoming fantastic at my new hobby of art, but how would I be as good as my role model, Lainey?…

Critical assessment of the article: Quantitative analysis by Auger Electron Spectroscopy 1 Introduction When the outer electron fills the vacancy left by an ionized electron in the inner shell, the released energy can be passed to another outer electron that causes further emitting of an electron with characteristic energy, this is the basic principle of the Auger electron spectroscopy (AES) [1]. Nowadays, AES is almost an indispensable tool in nanoscience research for its high surface…

James Chadwick, 82, of Bollington, England, passed away on July 24 while living in Cambridge, England. He died in his sleep of an unknown cause. Chadwick was a very important figure in history, having discovered the neutron in 1932. Chadwick was the son of John Joseph Chadwick, a railway storekeeper, and Anne Mary Knowles, a domestic servant. At a young age of 11, Chadwick won an entry to grammar school. He had two brothers, Hubert and Harry Knowles, along with two twin daughters whom he left…

The active region displayed in Figure 1 show a larger pore and several smaller pores in G-band. Bright points and several micropores are also visible. This active region was observed from 18:08 UT to 23:38 UT. However, there are three gapes from 18:42 to 19:08 20:21 to 20:47 and 21:59 to 22:26. Figure 1 shows the first image of the time series. Figure 2 illustrates the evolution of the fine structures at the inner part of the granules (i.e. towards umbra) at the pore boundary. Several dark…

Finders Keepers Have you ever lost money and were hoping someone would return it? Well, that's what Jack and Leah's problem is from the article “Finders Keepers” in the Scope magazine in January 2018 written by the editors. The problem is Leah thinks she should return the money and the other, Jack, thinks that he should not return the money because they found it so he thinks he has the right to keep it. I know if I lost my money I would want it back and I would hope someone would be kind…
