Learning Wednesday: Stunning Animation Of The Mechanics Of Breathing Watch A 12 Seconds Video

The human body never ceases to amaze me. The more I learn, the more I wonder, the more questions have to be asked and more research to do. I just adore the human body: its physiology, chemistry, pharmacodynamics, anatomy, biology.

Studying medicine is never-ending and has always been an honor and a scientific privilege from which I am deeply humbled.

Thursday Facts Let Us Think A Little?: Religion And Science

RELIGION AND SCIENCE ARE INCOMPATIBLE

They’re incompatible, because they both compete to find truths about the universe and life itself. There are some fundamental truths that believers have to accept in order to be religious. Scientists do not have to accept anything in order to be researchers, just observe, follow the scientific method and prove the fact. Religion is based on believes, not facts.

Saturday Night For The Free Thinkers: Let Us Think A Little?

In this gorgeous Saturday night, peaceful, with the sky so clear that I can see Jupiter and Saturn without binoculars, waiting for the Great Conjunction to happen on December 21th, 2020, this thought came to my mind: I cannot believe for the life of me that there are still apologetics for Creationism and Religion fanatics in this world of ours.

It is just logical. Using a little bit of math, simple mathematics. Nothing extreme, no rocket science involved:

Learning Wednesday: The Strongest Muscle In The Human Body And Stress

The Strongest Muscle in the human body (based on its weight) is the Masseter.
With all muscles of the jaw working together it can close the teeth with a force as great as 55 pounds (25 kilograms) on the incisors or 200 pounds (90.7 kilograms) on the molars!!!

Now it’s easy to understand why one suffers from headaches after clamping (Bruxism, grinding teeth) because of the effects of stress.

“The major religions on the Earth contradict each other left and right. You can’t all be correct. And what if all of you are wrong? It’s a possibility, you know. You must care about the truth, right? Well, the way to winnow through all the differing contentions is to be skeptical. I’m not any more skeptical about your religious beliefs than I am about every new scientific idea I hear about. But in my line of work, they’re called hypotheses, not inspiration and not revelation.” —— Carl Sagan

Aristotle was an advocate of reason. He stood for material truth. He was not so interested in Plato’s arguments that claim truth is more a spiritual ideal and not a material reality. Aristotle is called the father of science for that reason. He studied everything, observed how things worked.
