About a cloud which came to mind

Have you ever seen a cloud which looks similar to the human brain?

1. One way to view the problem is to say that one day a cloud came down and got inside our head, so that when it left and went up into the sky again, it had taken the shape of our brain.
2. An alternative way is to say that we tend to visualize clouds having the shape of our brain because clouds are similar in nature to our mind- light and obscure.

How much does a cloud weigh?

3. We usually refer to clouds as objects which are very light, so that they can float in the air.
4. However, on second thought, a cloud can be filled with water in the form of vapor. Water is a quite heavy element. For example if a cloud occupies a volume of, let’s say, a cube with edges 10m then the volume of the cloud will be 10³m³= 1000m³, thus it’s weight will be 1000 tons!
5. In fact, according to scientists, the weight of the average cumulus cloud is 1.1 million pounds (about 500 tons). This means that at any given moment there are millions of pounds of water floating above our head. That’s the equivalent of 100 elephants. [1]
6. But the reason why clouds stay afloat is because their content in water is distributed across a wide volume. In other words their density is low.

How much does a rock weigh?

7. It is estimated that granite weighs about 3 tons per cubic meter. [2] A more porous rock may weigh, let’s say, 1 ton per cubic meter. Thus a porous rock with a weight of 500 tons (that of an average cumulus cloud) will have a volume of 500 cubic meters. This is a cube with edges about 8 meters.
8. Now meteorites are rocks which can float in the air (thus the word ‘meteorite’).  The largest meteorite known is still embedded in the ground near Grootfontein in southwest Africa and is estimated to weigh 70 tons. [3] This is about 7 times less than the average cumulus cloud.
9. But if a rock weighs 7 times less than a cloud then why can’t a rock float in the air while a cloud can?

What weighs more, a kilogram of rocks or a kilogram of clouds?

10. If low density is what keeps clouds afloat in the air, micro gravity is what keeps rocks afloat in space. When a cloud condenses, its density increases, and it pours down in the form of rain. When a meteorite approaches the Earth, its weight increases because of gravity, and it hits the Earth.
11. But if a rock is as light as a cloud, or if a cloud of water or dust found in space is weightless, a rock and a cloud may be found side by side, floating in midair. 
12. After all, isn’t it true that a kilogram of rocks weighs as much as a kilogram of clouds?…

But how much does a thought weigh?

13. This is a possible answer: Thoughts ‘weigh’ on your brain in the same way that repeated movements tire your muscles. Thoughts arise when neuronal networks activate in a specific pattern. Each object, person, memory, concept, etc. has its own network of neurons that fire when the representation is called into thought. When we experience a ‘heaviness’ of thought, it’s typically surrounding one issue (be it object, person, memory, concept, etc.), and that’s because we keep firing the same network of neurons. So thoughts don’t have physical weight, but thoughts do have energy costs that can tire our neurons, the physical carriers of thoughts. [4]

14. How much does the human brain weigh? It is estimated that the adult human brain weighs about 3 pounds (about 1.5 kg). [5]

15. If we compare the human brain to a rock and a thought to a cloud then isn’t it possible that thought can be as heavy as the brain, since both the brain and its image (a thought), together with any other object, are pure representations in our mind (which we simply perceive as ‘physical’)?
