Here are some amazing science facts that will blow your mind. Read the full description to get a slight idea of everything. The next day you can be a hero to your friends.
1) Babies have more bones than adults.
Did you know babies have more than 100 bones than adults? When babies are born, at birth they have nearly 300 bones. Those are small bones with higher cartilage coverage between them. This helps to give extra flexibility to get pass the birth canal unharmed. And when they are growing, the bones are becoming stronger and fused. Cartilage coverage reducing. And in general, grown men only have 206 bones in adulthood.
2) Sodium explodes when it touches water.
Sodium and also all almost alkali metals are highly reactive. They can even react with atmospheric oxygen. Therefore it always presents as compounds. They do not exist as an independent element. Because of this high reactivity, it could blast when it is in contact with water. All alkali metals are one electron addition of their nearest inert gas. So, they highly tend to release that electron in order to be stable. Because of that, very high energy is released into the environment. That could lead to an explosion.
3) Our continents are still moving. They are not stationary.
The outermost layer of the is Earth crust. It is not a solid and continuous layer. It is split into massive pieces. Those are called tectonic plates. These plates are always in motion. Very slowly. That we can’t even feel. But they are. Some plates are moving away from each other and some are move towards each other. It means some countries are getting closer and closer and some are getting away.
4) Polar Bears are hardly visible in infrared cameras.
Infrared cameras use infrared wavelengths to identify objects. In normal words, they use heat wavelengths. Every object releases heat to the environment, especially living organisms. But polar bears live in a very cold environment. Therefore, their body is adapted to conserve warmth inside their bodies without releasing it to the environment. Because of that, the infrared wave signals coming out from polar bears are very low.
5) There are ten times more bacterial cells than human cells in our body.
Have you ever thought about how many microorganisms are there in our body? You won’t believe that we have at least 10 times more microorganisms in our bodies than our own cells. But don’t worry. All of them are not harmful. Some of them are very useful. The bacteria in our skin actually protect us from external bacterial infections. And also there are many bacteria inside our digestive system which helps the process also.
Don’t stop. You will miss some amazing science facts below.
6) You can’t taste anything without saliva.
The feeling of taste is created in the brain. It is due to the chemicals that are touching the receptors in the taste buds in the tongue. Therefore every food we eat needs to be dissolved in saliva to recognize the taste receptors. A fully dried tongue cannot identify any taste at all.
7) There were only two continents back then.
Scientists found that there was a huge supercontinent named “Pangea” during the late Paleozoic and early Mesozoic ears. Then this supercontinent was broken and separated into two large continents 335 to 175 million years ago. These two large continents are called “Laurasia” and “Gondwana”. Later at the continental drift, these two large continents again split into different continents that we know today. Laurasia split into Europe, North America and Asia without India. And Gondwana split into South America, Africa, Arabia, Madagascar, India, Australia, and Antarctica.
8) If all DNA of a human uncoiled and stretched, it will longer than the distance to the Pluto.
All genetic data is stored in the DNA molecules. The human genome contains 23 chromosomes. Chromosomes are highly coiled, stable DNA molecules. The average length of an uncoiled DNA molecule is calculated as around 5 cm long is a proven scientific fact. The human body has nearly 37 trillion cells and every cell has these 23 chromosomes in it. Therefore the total length would be nearly 2 x 1013 m. Which is longer than the distance to Pluto from Earth.
9) Water can be in three phases at one time.
It is hard to believe but, Water can be in three phases of gas, liquid and solid at one time. This point is called a triple point. This is a very important thermodynamic equilibrium. In simple means, this means water can freeze and boil at the same temperature at a specific pressure. Not only water shoes this property. A few other liquids also show this property.
10) Plants can alert neighbors when they are under attack.
Recent studies found that plants can release some volatile aromas that alert the neighbor plants about the attack. Now you might think what is the purpose of this alert? Plants can’t run away or hide. But they are not defenseless. They can produce toxic chemicals against insects. The smell of cut grass is also considered one of these alerting chemicals.
