Medicine had significantly improved by the start of the 20th century, then what specific aspect of Penicillin and antibiotics as a whole had such a major impact on saving human lives? And have humans been guilty of misusing antibiotics in the past few decades? […]
Accidents in the laboratory have played a key role in Dr. Alexander Fleming’s career. These accidents didn’t cause any harm. Instead. his trained scientific eye and the willingness to adapt to unexpected situations enabled him to make incredible discoveries. So, how did he accidentally discover Penicillin? […]
Toward the end of 19th century several physicians and scientists noticed certain inconsistencies with the theory of humors, which led to the development of the germ theory of diseases. What were these inconsistencies and startling discoveries, and why is the development of germ theory considered to be a revolution? […]
We know that small objects in the protoplanetary disk merged over millions of years to form planets. But not all objects in the disks became part of a planet. […]
We know how the solar system was formed. We also know that the planets grew out of a protoplanetary disk. Protoplanetary disks typically have masses that are only a few percentage of their star’s mass. They are also very thin, with a thickness of only about 10% of their radii. The disks contain gasses, like hydrogen and helium, and also micron-sized dust particles. […]
The concept of large bodies forming in space that lead a very ordered co-existence, some of which are made of rocks and metal, some of gas, and some of ices, can be daunting. But, nothing is ever by random chance. […]
Many think that higher cognitive functions are in charge of creating our actions and reactions. Maybe to some extent they are, but against genes and environment, they are not as strong as people expect. What makes us act and react? […]
The power of will misleads people into believing that they are autonomous individuals. However, when carefully studied, the genes and the environment prove it wrong. Are we fully dependent on the environment around us and the genes inside us? […]
It took a long time for scientists to recognize the science of psychology as a real science. They used to look at it as mere speculation and myths until the imaging technologies came to the rescue. How did they save psychology’s face? […]
There are misconceptions related to the twin paradox. We can use the concepts of special relativity and Lorentz transforms to explain twin paradox. […]
