While surfing the net, I came across this report by The National Science Foundation (NSF) of how well the American public knows basic science concepts. It turns out, not so well. In fact, one in four people are convinced that the sun orbits the Earth.
You can also know where your basic science skills stand compared to other Americans by answering the 10 questions from the NSF. It’s easy I got a perfect score you can too

1) The center of the Earth is very hot. TRUE or FALSE?
2) Continents have been moving their location for millions of years and will continue to move. TRUE or FALSE?
3) Does the Earth go around the sun, or does the sun go around the Earth?
4) All radioactivity is man-made. TRUE or FALSE?
5) Electrons are smaller than atoms. TRUE or FALSE?
6) Lasers work by focusing sound waves. TRUE or FALSE?
7) The Universe began with a huge explosion. TRUE or FALSE?

9) Antibiotics kill viruses as well as bacteria. TRUE or FALSE?
10) Human beings, as we know them today, developed from earlier species of animals. TRUE or FALSE?
1. The center of the Earth is very hot.
It’s really, really hot. It’s about 6,000 degrees Celsius (10,832 degrees Fahrenheit). The discovery of Earth’s inner core is attributed to Dr. Inge Lehmann, who was a seismologist in the 1920s. She studied at a progressive school in Copenhagen, which dared to assume that women could match men in intellectual capabilities.

2. Continents have been moving their location for millions of years and will continue to move.
Alfred Wegener must have been awesome at building puzzles. He noticed in the early 1900s that the Atlantic coastlines seemed to match up, like a puzzle. This led him to theorize that perhaps all the landmasses were at one time connected. He caught a good deal of flack for this crazy hypothesis, but it turned out to be true. Later work by Henry Hess on seafloor spread supported Wegner’s idea aboutPangaea.

3. Does the Earth go around the Sun, or does the Sun go around the Earth?
THE EARTH GOES AROUND THE SUN.
Copernicus is often credited with this discovery in the 1500s, but it was actually a claim made as early as 200 BC by Samos.

4. All radioactivity is man-made.
Radioactivity is the result of the decay of an unstable atom. Radioactive materialsare all around us and have always existed. Humans have also made a few, like Einsteinium.
Radioactivity was discovered byHenri Becquerel in the late 1800s by accident when he was researchingphosphorescence. Becquerel went on to become a Nobel Laureate.

5. Electrons are smaller than atoms.
The discovery of subatomic particles has been a group effort. The latest piece of the puzzle has been the discovery of the Higgs boson. Electrons were discovered by J.J. Thomson in the late 1800s, and because they are a subatomic particle, it’s safe to say that they’re smaller than an atom.

6. Lasers work by focusing sound waves.
The first laser was made by Theodore Maiman in 1960. Interestingly, he built it because he just thought it was cool. Maiman has said, “A laser is a solution seeking a problem.” We now use lasers for everything from scientific applications to printing.

7. The universe began with a huge explosion.
The Big Bang Theory took root in the 1920s with the help of Georges LeMaitre, who laid the theoretical groundwork based on Einstien’s Theory of Relativity. However, he had no data to back up his theories, just the mathematical model that it was possible, so most scientists ignored him.
Even Einstein wasn’t on board with this new idea just yet, but by the end of the 1920s, Edwin Hubble added the data to support this idea. Hubble observed that galaxies that were further away were moving faster than those closer to use supporting the idea of an expanding universe.

8. It’s the father’s gene that decides if the baby is a boy of girl.
Sorry, ladies. This one is always up the the guy. In 1902, geneticist Walter Sutton discovered the sex chromosomes. Not all animals determine sex by the same biological mechanism. Some organisms have a completely different system, and this threw a wrench in convincing the scientific community that the X and Y chromosomes determined the sex of a baby. However, this got sorted out by E.B. Wilson, who discovered two major mechanism of sex determination that accounted for all species.

9. Antibiotics kill viruses as well as bacteria.
Viruses are one of the strangest and most awesome things. I say things because they’re not living, but rather just a piece of DNA or RNA floating around in a protective shell looking to break into your body and take over you cells. Dmitri Ivanovsky was the first to discover these alien-like infectious agents in 1892 while looking to solve the mystery of infected tobacco plants in the Ukraine. Because viruses hijack host cells, they are not able to be attacked by drugs like antibiotics. To do so would mean that your own cells would be targeted for destruction.

10. Human beings, as we know them today, developed from earlier species of animals.
There’s so much evidence on this one that it could be a book. In fact, there already are thousands. Thoughts and ideas about the evolution of humans began in the scientific community in the 1700s with Georges-Louis Leclerc. Over time, the idea was ruminated on by many scientists, but Darwin’s seminal work On the Origin of Species gave it traction. Darwin knew that his proof of evolution would cause such an uproar that he was silent about his data for more than 20 years. He only published it because Alfred Russel Wallace found the same evidence and was about to publish his work. Darwin may have wanted to avoid controversy, but not at the expense of infamy.
