How does the power cable charge the mobile phone? It's decided to be magic! According to a Pew Research study, many of our fellow Americans have no idea how the world works. Carbon dioxide also contributes to global warming.
Readers can answer the interactive quiz here before proceeding with this article . Pew's quiz got a lot of attention this week. International scholastic ability tests have confirmed that the poor education system of Americans creates a terribly imbalanced and ignorant society .
Here are some of the most notable questions that respondents couldn't answer correctly.
Less than half of high school graduates and above know the cause of global warming
Forty-nine percent did not identify "carbon" as the cause of climate change (other options are hydrogen, helium, and radon). This is not a question of whether the cause of global warming is human. Just in case, what is warming the surface of the earth.
The result that also plagues those who think democracy is cool is that about one-third of the respondents didn't know the basics of drug testing. Thirty-three percent of high school graduates and younger said they should administer the drug to all subjects (rather than half of them in the control group).
Nano means small
In fact, nanorobots are not very large robots, cold robots, or hot robots. Nano is a prefix that means very small. I'm worried when an evil villain will pollute the water with a mind control robot. Or will our government really discuss regulations on air pollution and pesticide spraying?
"If nanotechnology does not effectively communicate the potential risks to the environment, it threatens proper environmental regulation and secure investment in the private sector," explains a paper from the Yale University Institute for Cultural Cognition. PDF ].
Electrons are smaller than atoms. Lasers cannot be made from sound
About 33% over the age of 65 did not know that electrons are smaller than atoms. Given the glorious history of nuclear propulsion during the Cold War, you might notice that the object orbiting the central sphere is smaller. Overall, less than half (47%) got the correct answer.
Other interesting facts. Sound does not produce dazzling light. The laser is visible. Despite this fact, nearly half of Americans believe that lasers are made from sound.
Bacterial resistance exists
Now we are slowly heading towards the global epidemic of drug-resistant bacteria . The more we vaccinate cattle destined to become Big Macs, the less our defenses will be. The majority of people (77%) recognize that bacterial resistance is more of a problem than bacterial addiction (which is not the case). The percentage of correct answers for high school graduates and below was only 58%.
