- The only part of the body that has no blood supply is the cornea of the eye. It receives oxygen directly from the air.
- The human brain has a memory capacity equivalent to more than four terabytes on a hard drive.
- A newborn child can breathe and swallow at the same time for up to seven months.
- Your skull is made up of 29 different bones.
- Nerve impulses sent from the brain move at a speed of 274 km/h.
- A single human brain generates more electrical impulses in a day than all the telephones of the world combined.
- The average human body contains enough sulfur to kill all the fleas on the average dog, enough carbon to make 900 pencils, enough potassium to fire a toy cannon, enough fat to make seven bars of soap, and enough water to fill a 50-liter barrel.
- The human heart pumps 182 million liters of blood during the average lifetime.
- 50,000 cells in your body died and were replaced by new ones while you were reading this sentence.
- The human embryo acquires fingerprints within three months of conception.
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.
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.
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:
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.
“Be ware of humans instead of be aware of dogs” – There are dogs with a high bite force but we can be very dangerous too. 👼
I love Carl Sagan scientific life. He was a scientist who, despite his passing on December 20, 1996 keeps on educating us with his intellectual abilities and philosophical analysis on life.
Books, articles, journals signed by several Nobel Prize winners, conferences about science, astrophysics, astronomy, philosophy and more.
Carl Sagan was a passionate advocate of scientific and critical thinking.
“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
Along the way I have questioned and answered some queries that have satisfied my curiosity. And still, I am willing to change my mind if they are refuted with intelligence.
For example, I am extremely offended by some of the things that are written in the Bible and the Qua’ran and other religious books or booklets.
But more offended I am by the people who defend those biblical assertions and permissions to commit horrible crimes against humanity. I condemn and reject those writings.
Because humanity doesn’t deserve to be confused and abused by the fairies, by organized religions that all they do is to cause harm and false sense of morality.
