The strongest of the four fundamental forces known to modern physics is called, well, the strong force. At the same distance it is 137 times stronger than electromagnetism and 1038 times more powerful than gravity. The strong force keeps sub-atomic particles attached to each other.
Modern physicists who are also modern parents know better. The strongest force in nature is the one that keeps teenagers attached to smartphones.
A lot of energy is required to separate them and the outcome is exothermic, exosonic and often explosive. I have written about my experiments with this area of physics in a Debates with my Daughters column.
So when some of my colleagues wondered whether the Taliban 2.0 regime in Kabul would ban smartphones, I responded that it would be quite unlikely. Telephone penetration in Afghanistan in the 1990s during Mullah Omar’s days was negligible. It is over 70% today in a country where half the population is less than 18 years old. The Talibs themselves are probably more addicted to smartphones than the other addictive substances available in their country; although like people around the world they are bound to claim that they need the phone for work-related purposes.
