anonymous asked:

could you explain those stick figure things that you use to draw out chemicals? Sorry if it's a stupid question, I don't get them :(

Yes of course! Not at all a stupid question, chemistry is hard.

The ‘stick figures’ are called skeletal formula, and it is essentially a short hand way of drawing organic (carbon-containing) compounds.

I drew out an example using a chemical called propane:

As you can see, in skeletal formula all the hydrogens are stripped off, leaving you with the just the carbons. Every point on the skeletal formula represents a carbon; propane has 3 carbons so it’s skeletal formula has three points to represent them. 

But the carbon chain isn’t always that simple, and in most of my infographics, the molecules can get quite complex. Other groups/elements may be added in various places, represented by their chemical symbol- I’ve used an example from this infographic of the neurotransmitter GABA:

You can still see the basic carbon chain in the skeletal formula with the 4 carbons, just with the extra add-ons. I hope this explained it enough! If you still need clarification this video goes into more depth.

I.

I just want to be swept off my feet.
To be caressed and kissed like I am needed .
Like my lips are a hunger that can’t be cured.
A BURNING desire
A fire that can’t be put out between us….
CHEMISTRY.

I haven’t forgotten your kiss.
How passionate. Sweet and soft.
I would like to forget ..
But I always question what if.

TOP TEN MOST IMPORTANT FEMALE SCIENTISTS THAT EVERYBODY NEEDS TO KNOW ABOUT

1. Ada Lovelace - A writer and mathematician and the daughter of famous writer Lord Byron, she is known historically as the world’s first computer programmer - even though computers weren’t invented for more than a hundred years after she died.

2. Marie Curie - A Polish chemist and physicist who, along with her husband, discovered both the phenomenon of radioactivity and two new elements (Radium and Polonium). She was the first woman to win a Nobel Prize, the only person ever to win twice in multiple sciences, and gave birth to two children who themselves went on to win a Nobel Prize, making the Curie family the recipients of five different Nobel Prizes. 

3. Rosalind Franklin - While today it is two men, James Watson and Francis Crick, who get the credit for having discovered deoxyribonucleic acid (better known as DNA), it was actually a woman - Rosalind Franklin - who discovered the structure and properties of DNA. It was Franklin who theorized that DNA had a winding staircase structure, and she believed that phosphorus played an important role in the shape of DNA. Watson and Crick disagreed with her, though they later took the credit for her theories and discoveries. 

4. Jane Goodall - Considered to be the foremost expert on chimpanzees on Earth, Jane Goodall is a British primatologist, ethologist, and anthropologist. She has done considerable work in the area of conservation and ethics and contributed greatly to our knowledge of primate behavior. 

5. Gail Martin -  After graduation, Dr. Gail Martin pioneered the field of stem cell research by discovering the method that we currently use to grow stem cells in a petri dish, which had previously been impossible. She also discovered that it was possible to harvest embryonic stem cells and, in fact, coined the term ‘embryonic stem cells’ itself.

6. Françoise Barré-Sinoussi - A French virologist who discovered that AIDS was caused by a virus, not some kind of “gay cancer”. Her contributions helped change public perception of HIV and AIDS as a “gay disease”, and likely saved many thousands of lives when she recommended ways to stop transmission between sexual partners (such as using condoms during sex). 

7. Mary Claire-King - An American geneticist at the University of Washington, Mary Claire-King has studied the genetics of a wide range of topics, including HIV, lupus, deafness, and ovarian and breast cancer. Even in university, she was making waves: her thesis paper proved that the human genome and the chimpanzee genome were 99% identical. Later in her career, she helped pioneer a new type of treatment for breast cancer.

She also used her skill as a geneticist to help identify victims of human rights abuses by identifying children who had been illegally stolen from their families during wars, such as the Dirty War in Argentina. 

8. Marie Tharp - A geologist in the 1970s and the only female in her entire department, Marie Tharp single-handedly rewrote everything that we currently know about geology today after a single discovery that she made one night. She hand-drew a map of the entire ocean floor and ended up discovering the Mid-Atlantic ridge, a series of underwater mountains and volcanoes which eventually caused a paradigm shift in the field of Earth sciences and led to the discovery of geological phenomena such as plate tectonics and continental shift. It took her years to gain credence for her theory, because her all-male department refused to accept her conclusion (until one of them, you know, actually took a look at her data). Both Marie Tharp and Annie Jump Cannon were mentioned by Neil deGrasse Tyson on different episodes of ‘Cosmos: A Spacetime Odyssey’. 

9. Annie Jump Cannon - A deaf astronomer, Annie Jump Cannon and a group of other women were responsible for the development of a classification system based on color that we still use to this day to identify stars by.

10. Florence Nightingale - Most of us have probably heard this name before; and while she technically didn’t discover anything, she was single-handedly responsible for some reforms in the field of nursing that had enormous impacts on the way that nurses treat their patients, some of which are still practiced today (especially in undeveloped nations, where access to medical care is often sparse).
