Seedless Fruit Production

If I swallow a watermelon seed, a new watermelon will grow in my stomach, right? Just kidding! It is a good thing that we have seedless watermelons. What....if there are no seeds. how do we make more of them? These days, you see way more seedless fruits than seeded. Seedless grapes, oranges, watermelons, come to mind. But, natural bananas have seeds in them, so do cucumbers.

The fruit is, by nature, a matured ovary around a seed; the flesh of a watermelon or apple is a part of that ovary. So, if it's not natural, then what is a seedless fruit? Seedless plants have been around for milllennia. Some strains of grapes were documented in ancient Roman times that didn't produce seeds. And in 1872, seedless navel oranges were brought to the US from Brazil. They were sourced from a clump of freak orange trees, accordin to an article of the New York Times, from 1902. And, thanks to the American farmers, they grow everywhere today.

So, it seems that the seed gene of watermelon has a relationship with the time of maturity and sweetness, while for the orange plant, it is juiciness.

Why Do Glass Windows Shatter During Fire?

You might have noticed in movies and also in real life that whenever there is a fire inside a building, the glass windows crack and break. The openings of the windows in the walls of the room on fire play a key role in the spread of fire. Windows are those parts of the buildings that generally have less resistance to fire in comparison to that of the walls. During a fire, there is a increase in temperature inside the room. The glass pane is not subjected to uniform heat from the fire. Glass windows are fitted within the frames, and the thickness of the frame is larger in comparison to that of the glass pane. There is an intense heat flow that is suddenly experienced on one side of a glass pane. As a result, the heat focussed on the central region of the glass causes it to expand. While the edges of the pane happen to be relatively cooler, which induces stress in the material. This shifting gradient is known to shatter the glass to pieces.

Is Mount Everest The Tallest Mountain On Earth?

Everyone knows that Mount Everest is the tallest mountain on Earth. But, this is actually true, only if you measure the height of the mountain from the sea level. If you measure it from base to summit, it is actually the world's second tallest mountain. The first place goes to Mana Kea in the Hawaiian Islands - a one million-year-old dormant volcano that last erupted 4,000 years ago. Its peak is only 13,802 feet above sea level. As the bulk of the mountain is under water, from base to summit, it is 33,500 feet tall. That makes Mauna Kea almost 1 mile taller than Mount Everest. Because of its altitude and thin and clear air, it is a great place to see the stars. So, Mount Everest might not be the tallest or the farthest from Earth's centre. But, it is still the go to mountian for the extreme climbers worldwide.
