Lavoisier, The Father of Modern Chemistry

Antoine Lavoisier was born in was born in Paris on August 26, 1743. He was one of the greatest scientists in chemistry. He also learned more sciences and have wonderful works in each of them, even his major is still in chemistry. He was the pioneer in stoichiometry and the one who enlightening people from a mistake called phlogiston. Unfortunately, he was convicted as guilty by Revolutionist and was guillotined. We will not know about oxygen if Lavoisier never research about combustion. We maybe will still following phlogiston theory to explain why the mass of the burned wood is different with its mass before burned. To celebrating this year as "The Year of Chemistry", let's see more about his greatest contributions in chemistry world.

Easter Egg

Talking about Easter is talking about Easter egg. It's usually a boiled egg. It symbolizing the life and salvation that Jesus give to humankind by His sacrifice in the cross for Christian belief. Egg is also a good food. It's a good resource of nutrients for your daily intake and it's good to put it in your diet. You can get enough amounts of nutrient from egg, whether it's boiled or fried. Wanna see how much nutrients you can get from a 100 g egg?

Green Trend (?)

"Green" is a popular color between all colors nowadays. You can find it anywhere in any products, from foods to gadgets. It seems environmental issue is a great promotion for selling products. But how does "green" relate to those products? Well, it seems most of the products that using "Green" term is truly "green". But some other are only put it for promotion, while the truth is far from green at all. So let's see what are "Green" and its correlation to our environment.

Nuclear Power and Environmental Issues

The pursuit of a new energy has begun from last century. It has been a global concern that the deposit of fossil fuel will empty in no time. That's why the scientists trying to find the alternative energies to keep support our live. One of these energies is nuclear energy, an energy that rest inside each atom in each material as their potential energy. Radioactive elements offers a chance to get energy we need from natural process that only happen to them: Decaying. Because their instability, the radioactive elements tend to release their neutrons and also great amount of heat energy as radiation. This energy then converted as electrical energy by using it to vaporize water that turn the turbine to generate electricity

It seems that the nuclear power is the best alternative to meet energy need for now. But after an accident in Fukushima I Nuclear Reactor Plant, it seems we need to reconsider it again. Here are some of the negative sides of nuclear power:

How Drug Works: The Simple Explanation

How many of you when got a headache grabs an aspirin and used it? Aspirin has been used as a drug for headache for years. It works just like other drugs: binding itself with its receptor in cells and tissues. It’s a complex process, but can be explained in a simple way. So let’s see how it works!

Forensic

If you ever watch CSI you'll noticed that for making a fingerprint visible they do something called fumigation. For this they need a chemical compound called cyanoacrylate. It's a usual chemical compound we found in our daily life, since it's the major compound of Super Glue. In CSI, they heating this chemical compound and then the fumes come out and make the fingerprint visible. Then, how this trick works?

Tricky Chemistry

Have you ever seen how a mere water turns into wine? Well, of course it's not like in Bible. It's just looks like the water transform into wine, or that's how you saw it. I found this article about simple magic trick that using chemistry as its basic. It using some sodium carbonate and pH indicator called Phenolpthalein to do this trick. The article itself has explained how it could happen. But let's see it more deeply than just a how-to. Welcome to the tricky chemistry :) .
