15 Amazing Facts About Science
science offers countless fascinating facts to us every day
It uncovers astonishing truth across Biology, Chemistry, Physics, astronomy and more. Even science plays an important role in our lives today.
Here we have gathered 15 unknown facts from science.
Let’s dive in!
Fact 1: oxygen production in oceans
Tiny Marine algae (phytoplankton) and Seaweed in the ocean produce 50% of Earth’s oxygen through photosynthesis. This Biology highlights Ocean roles in life science.
Fact 2: The superpower of stomach
The human stomach produces hydrochloric acid (HCl) with a very low pH ranging from 1.0 to 2.0. This acid of stomach can dissolve razor blades over time. This acid reacts with the metal like Iron, chromium, Nickel etc. to form Salts and release hydrogen gas to erode the metal.
Fact 3: Animal has their own GPS
Sea turtles and birds can Sense Earth’s magnetic field to allow themselves to navigate long distances. It is their biological ability i.e. called magnetoreception. They use this power for migration.
Fact 4: More trees on earth than stars
Yes, it is true. A 2015 study estimated around 3.04 trillion trees on Earth whereas NASA estimated that there are 100 to 400 billion stars in the Milky Way galaxy. So, there are roughly 400 to 800 trees for every star in our Galaxy.
Fact 5: Venus’s spin mystery
Do you know, a single day on Venus is longer than its year! It sounds weird but it’s true. Venus rotates extremely slowly on its axis. so, it takes 243 Earth days for a day, but it rotates comparatively faster around the sun in the opposite direction and for that it takes 225 Earth days for a year.
Fact 6: Sun’s Heat vs Lightning’s Heat
Lightning’s heat is extremely hot (30000 degree Celsius) but it is only for a fraction of a second whereas Sun’s surface is much cooler( 5000 degree Celsius) than Lightning’s speed.
Fact 7: Radioactivity of Bananas
Bananas contain a small amount of potassium which is the radioactive isotope of potassium-40. Thus, bananas are slightly Radioactive (about 0.1 micro sieverts ). Oh! Don’t worry, it is harmless amount of radioactivity.
Fact 8: Sharks existed before trees
Sharks are considered as “living fossils” because they appeared in the Earth’s oceans 400 million years ago. when Sharks first appeared in the earth, land was mostly barren.
Fact 9: Honey never spoils
Did you know, Honey is the only food that never spoils! Due to its low moisture, bacteria and mold can’t grow. Due to its highly acidic nature, most spoilage-causing microbes can’t survive. Moreover, Bees add glucose oxidase that produces hydrogen peroxide. It is a natural antiseptic that fights against bacteria.
Fact 10: The unique biology of Octopus
- Octopus have Blue Blood because it contains copper based hemocyanin.
- Octopus have nine brains.
- Octopus have three hearts.
Fact 11: Science behind power of brain
Our brain can generate enough electricity every day to power a small light bulb. An average of 20 watts of electrical energy is produced by the chemical processes of the neurons in our brain.
Fact 12: More bacteria than cells
our body has trillions of human cells, but the number is not more than microbial cells. So, our body contains more bacteria than human cells.
Fact 13: Heart of a Blue Whale
The size of a blue whale’s heart is compared to a small car or a golf cart. Approximately the weight of a blue whale’s heart is about 400 Pounds or 180 kgs i.e. similar to a Gorilla.
Fact 14: The length of the Eiffel Tower
The length of the Eiffel Tower increases in the summer due to thermal expansion. It grows approximately 15 cm (6 inch) taller in summer.
Fact 15: Sound Travels faster in water
Yes, sound Travels 4 to 5 times faster in water than in air because in water, molecular density is greater than in air that allows vibrations to transfer more quickly in water.
The sound’s speed in air is 343 m/s whereas the sound’s speed in water is about 1480 to 1530 m/s.
