This thread is ridiculous. A value makes no sense without a unit: for example, I can say 3. So? What does that number mean? It means there are 3...what?
However, I can add the word 'grams' onto the end, which makes the number mean something 3g.
Then I say 4. 4 kilograms. 4kg and 3g.
If I just take the numbers with no context at all, then I'd get 7. But with the units, I get 4003g. Very different answers, but it doesn't take a genius to see that the latter is correct. Why? Because the units are vital to the equation. The unit is what makes the sum actually worthwhile.
Then we get onto the raindrop analogy. The unit is what? 1 raindrop+1 raindrop. Ah, but what constitutes a raindrop? Water that falls from the sky? Does that make mist a raindrop, or a cloud a raindrop?
Take two lego bricks. Put them together. Does that mean you just have one lego brick? No, because there is a set value for a lego brick: the unit being one dot, or four dots, etc. The truth is 'raindrop' is not a valid unit, for a raindrop has varying sizes. If you take a value for a raindrop as, say, 1ml, then you can get 2.024542656 raindrops as the result, or some such thing. Why? Because a unit of mathematics has a fixed value. The number 1 has the fixed value 1, the number 3 has the fixed value 3, the number 3.1415926535897 has the fixed value 3.1415926535897. The unit here is a numerical value. But when you discuss subjective terms such as raindrop, then anything can be true. Is the whole Ocean just one raindrop? Or is it a compilation of many, many drops? Is a flood caused by only one raindrop?
To revisit the lego example: two bricks. Place them together, and they are one mass, but two bricks.
And besides, what the

does this have to do with FET?
