Atoms can be crushed, as can quarks and electrons. However, you are speaking in a theoretical way because nobody has proof that infinitely small particles exist. It is actually depending on the substanse of the particle and which of the many dimensions it responds to. At the level of quantum physics, particles alter between energy and matter, so, if you are talking about quantum physics, no they cannot be crushed. Now, remember that there is enough matter in your fingernail so that if it was all packed closely together it would be smaller than an atom. So, you can simply unpack all the matter and then crush it. I have no idea why you would want to, tough. It is a waste of energy. There is a simpler answer. It's important to get some definitions first. Crushing implies making smaller. Infinitely small is an abstract, not concrete concept meaning small to an infinite degree, which means a size that cannot be made smaller. Therefore, the answer is no.
No. Infinitely Small implies something that is as close to zero as it can get without actually being zero - think of a positive or negative fraction with an infinitely large denominator. Infinitely Big implies something that is as far away from zero as possible, and then some: negative infinity or positive infinity. You can think of infinitely small as being the reciprocal of (one divided by) infinitely big.
du refers to a differential part of u, which is infinitely small.
You can put an infinite number of square units on any surface if the unit is infinitely small
If you have a strange dream of all encompassing but infinitely small power, then it means that you are frighten.
It is infinitely small.
Infinitely small.
infinitely small
Infinitely many. The length of one pair of sides can range from infinitesimally small to infinitely large.

A small can of crushed pineapple would vary. Depending on the brand, the can will weigh anywhere from 4 ounces to 8 ounces. A small can is not a standard size for every brand.

To further expand on this question, why couldn't the universe have started from a large mass rather than something so small? If you light a stick of dynamite, and then somebody from the other side of the galaxy looks at it through a telescope but only see's the couple of milliseconds after the initiation of the explosion, would they theorize that you can cause explosions from infinitely small points as well?
