It is human nature to make an effort, to go, to see, to understand. Exploring and experimenting is not a choice, it is a necessity.

What are some mind-blowing scientific experiments?

 In 1998, two scientists at the University of Pittsburgh, Pennsylvania, did something that sounds almost impossible. They successfully convinced people that a dummy rubber hand was part of their own body.

This is how it worked.

The scientists asked each participant to sit on a chair by the table. They would ask the participant to place one of their hands on the table while the other hand was hidden out of sight, either under the table or behind a screen. Then they would place the rubber hand in front of the participant, where their hidden hand would normally have been.

Next, they would stroke both their hidden hand and the rubber hand simultaneously with a paintbrush. Strangely, within moments the participants started experiencing the touch on the rubber hand. When asked where they were feeling the sensation, they pointed towards the rubber hand.

The key condition for the illusion to work was that the paintbrush strokes had to be in sync. If the strokes were out of sync, the illusion vanished.

After the initial success, the same experiment was replicated many times with slight variations. In some tests, researchers even hit the rubber hand with a hammer and participants would react in shock and distress, despite no real injury.

The experiment demonstrate an interesting thing that our brains can be tricked into believing that an object is part of us, if the conditions are appropriate.

What is the scientific explanation for the cold temperatures in temples, especially in India?

 Step barefoot into a traditional Indian temple on a scorching 40°C (104°F) day, and it feels like an air-conditioned room. This dramatic chill is a masterclass in ancient thermodynamics.

The primary mechanism at work is thermal mass. Historic temples are constructed from dense, heavy stone, such as granite, sandstone, basalt, or marble. These materials have a high specific heat capacity, meaning it takes a tremendous amount of energy to change their temperature. During the day, the thick stone walls absorb the sun's radiant heat very slowly, preventing it from penetrating the interior. By the time the stone absorbs enough heat to warm up, the sun has set, and the walls radiate that energy back out into the cooler night air.

The layout of a temple is intentionally designed as a series of thermal buffer zones. The outermost courtyards bear the brunt of the heat, while consecutive inner halls provide increasing shade. At the very center lies the garbhagriha (sanctum sanctorum). This innermost chamber typically has the thickest walls, the fewest openings, and is completely shielded from direct sunlight.

Above the garbhagriha sits the vimana or shikhara, a tall, tapering spire. These spires act as thermal chimneys. As the limited amount of warm air inside the temple rises, it moves up into the high ceilings of the spire. This upward movement creates a slight negative pressure below, drawing cooler air in through the lower, shaded entryways and corridors to create a continuous, gentle draft.

Water plays a crucial final role in lowering the ambient temperature. Traditional temples are built alongside large water tanks or stepwells (kalyanis), which pre-cool the breeze blowing into the complex. Inside, the stone floors are routinely washed with water, and thousands of visitors walk through barefoot, often with wet feet from mandatory washing stations at the entrance. As this surface water evaporates, it absorbs latent heat from the stone, chilling the floors to the point where they remain noticeably cool to the touch even at midday.

The interior of a traditional garbhagriha features massive stone columns and thick walls that isolate the central sanctum from external heat. Photo by iMahesh is licensed under CC BY-SA 4.0.

What are some scientific discoveries that have changed the world?

 According to Isaac Asimov, the truly important scientific discovery was when Benjamin Franklin published his paper in 1752 stating that "lightning is an electrical phenomenon."

As they say, it's no exaggeration to say that this changed everything. Previous scientific discoveries were only important to other scientists; they had no bearing on humanity as a whole. When Galileo published his geocentric theory, the church opposed it, but it didn't make much of an impression on the general public.

However, Franklin's discovery led to very practical applications.

This is one of Franklin's "lightning rods," a device designed to prevent lightning from striking buildings.

This spread like wildfire, like, "Oh, I don't know, maybe it was lightning?" Within 10 years, churches were the only ones not using lightning rods, because they believed lightning was the work of God and a specific reward from Him. However, after lightning struck a church where gunpowder was stored, (perhaps because God likes churches?) churches also began to adopt them.

The idea that science can solve real-world problems began with lightning rods, and before we knew it, the strange phenomenon of "electricity" came to be used for all sorts of purposes.

For motors that do not require flames,

Bright, inexpensive, and safe lighting,

For extremely fast computers, etc.

What are some exceptional scientific photos?

 This photo shows a winner!

Of the approximately 200 million at the starting gate, he was the strongest and the luckiest to reach the intended destination: the egg cell.

At the moment he crosses the finish line—this is hard to believe—the photographer captured the exact moment of penetration:

After the sperm has penetrated, the egg closes its 'doors' to all latecomers.

The photos above and the following were taken by Swedish photographer Lennart Nilsson, who observed and documented the incredible developmental process of human embryos from fertilization to birth. To do so, he adapted a cystoscope—a device commonly used for bladder examination—with a lamp and a special camera.

On the 18th day after fertilization, the heart of the embryo begins to beat.

(Aristotle already knew that the heart developed first; he used 21 chicken eggs and opened one every day. Because he saw the heart first, he argued that it must be the seat of the psyche—he had other arguments as well).

The embryo after 22 days. The gray area will later form the brain.

After 10 weeks:

Another month to go and then another race begins, one that lasts a lifetime:

What scientific photos are hard to believe but are indeed real?

 These photos are hard to believe but they are indeed true.

Before you look at them, know that the traits demonstrated here all have a scientific explanation such as, genetic deformities and adaptation to some illnesses that have made the body live with the affected limbs.

Let us begin:

1. The leaping Cuban Crocodile

This is the Amazon’s deadliest predator after the Green Anaconda and the black panther. It can leap a record 9 meters high and grab prey from the trees into the Amazon river. It is also as fast in running as a leopard.

2. The longest nails in the world

Beautiful uh? or just scary. However you view it, nothing surpasses the genetics behind these long nails.

3. The widest eyes in the world

If I did this to my eyes, I would simply cry and go blind. I wear glasses and this would just hurt me drastically.

4. The world’s longest neck

Even a snake would mistake you for one of them with a neck that long. How does she shower? A very long neck indeed. A genetic blessing.

5. The tallest and shortest man

Uh? How tall is your husband again? How short is your wife? Look at these two.

6. The Jesus lizard that leaps

Jesus walked on water, this lizard leaps on water. It can run faster than a cheetah and leaps for distances as long as the water goes. It has beautiful webbed feet that allow this feature. They work like hydraulics on a car. It also feeds on beautiful butterflies. It is…beautiful.

7. The two-headed snake

Hehe. This one has only two heads, here in Kenya, puff adders have three heads. However, the two-headed snake is the most common. It is actually very harmless, unlike the Kenyan puff adder or adders.

8. The longest tongue

She is pretty and lizardy. I like that tongue. We could kiss all day. However, it would creep me out at night when I am in bed with her.

All the above are scientific traits in man and animals that have developed into adaptation features for the respective affected creatures.

Our world is very interesting.
