Tattoos are usually believed to be a permanent expression of feelings on your body forever, but a company called Freedom-2 has created tattoos that can be removed in one laser treatment. Traditional tattoos have to be removed in multiple laser treatments and even then are not fully removed. Synthetic tattoo ink was researched but has been deemed potentially cancerous because of it containing phosphorous. The tattoo ink that Freedom-2 has created uses polymer, which is a much lower level of pigment compared to traditional tattoo ink. The new removable tattoo ink will change the whole concept of tattoos and their timelessness.

Crude oil is very useful, but in it natural solution it is useless. In order for crude oil to be used it must be separated into its various hydrocarbons. The process that is used to separate crude oil is called fractional distillation. Each hydrocarbon separates out at a different temperature the first hydrocarbon separates out at 330 degrees Celsius and the last hydrocarbon separates out at 85 degrees Celsius. There are five different temperatures that the hydrocarbons separate out at. Even when the crude oil is separated into its five components those things can be separated into more compounds. Plastic and asphalt can be made from crude oil as well as other things used today.

The article about redefining the kilogram was interesting. I think that the fact the kilogram is the only SI base unit that is still being defined by a physical artifact rather than an unvarying physical property of nature, is weird because if every other unit of SI measurement does shouldn’t the kilogram also. I think that it would be smarter for the scientist to assign the kilogram with a more dependable way of measuring the kilogram, because the physical kilograms are losing mass little by little and the change of the original mass is bad.

Afryea, I agree with your thoughts. Good post. 5 stars. MW

This article was really very interesting. I am curious as to how the scientist figured out how the stars form he elements, I mean did they create some stars in a lab and observe what happened? I think that the fact that humans are made out of the elements from stars is weird because it’s hard to imagine humans coming from stellar bodies. The article talked about how most stars only make it up to the stage where they produce iron which is only 26th element out of 117 and how the heavier elements only last for fractions of a second after the star collapses.

Afryea, Yes fascinating stuff! good thoughts. 5 stars. MW

This mole day holiday is quite interesting and funny. I think that the history of Avogadro is quite interesting, the fact that he was unappreciated while he was alive, and then proved useful only two years after his death, is a common trend in the early lives of intelligent forward thinkers of those days. I think that his ability to not look for acceptance by the mainstream scientific community showed his confidence in what he was doing, he knew he was correct and didn’t need anyone else’s opinion.

Afryea, So true that people are often not appreciated until after their death! 5 stars. MW

This article is really informative. It says that dust explosions are started when the oxygen from the air, air particles and dust mix and are lighted by even just a spark of electricity a huge dust explosion can ensue. The dust particles are so small that the ratio to the air particles and oxygen is small so it is easy to get a balanced combustible product from the reactants. The thing that surprises me is that it only takes one-eighth of an inch of dust on the floor to start a fire.

Afryea, It is amazing how little dust is needed to cause a problem. I wonder if anyone's house every blew up due to dust! 5 stars! M

The things that I knew were: · That sulfur hexafluoride is made from one sulfur atom and six fluorine atoms. · A balloon filled with helium gas tends to deflate more quickly as the helium leaks out, but I don’t know why this is. · A balloon filled with air stays more or less the same from one day to the next.

The things that I learned from the article were: · That the gas that makes a person’s breath sound deeper when ingested is called sulfur hexafluoride. · When people breathe in gases like helium and sulfur hexafluoride they are not getting oxygen so that it they keep inhaling the foreign gases without taking a breath of fresh air they are suffocating themselves inadvertently. · The reason helium balloons deflate so quickly is because helium atoms are moving so fast that they can leak out quicker than air molecules on the outside can leak in.

Afryea, Looks good. You definitely picked up on some good stuff! 5 stars. MW

Three things that I knew were: · That different colors had different frequencies, red is low frequency and blue is higher frequency. · Light behaves as a wave and is made up of ‘particles’ called photons. And that the energy of the photon depends on its frequency. · The eye is a photo sensor, in that visible light pushes around the electrons in a cis-retinal molecule. Three things I didn’t know: · That there are three types of motion sensors, the only type of motion sensor I knew about was the photo sensor, because in all the movies it’s always beams of light rotating through vaults. · What the “photoelectric effect” was. It’s “when light of sufficient energy is shined on a given surface, it can cause electrons to be ejected.” · That Einstein won the Nobel Prize in physics on his work in photoelectric effects, I only knew him for E=mc ²

Afryea, Well done! You knew quite a bit! 5 stars. MW
