Could anyone give me the names of universities that offer this major, if there is any? Thanks in advance :)

1 AnswerMathematics7 years agoA question about using BJT transistors as amplifiers?
In a BJT transistor which has either an npn or pnp structure, it seems to me that the part responsible for the whole amplification process is the emitter-base junction, which when forward biased acts as a diode and therefore the current increases exponentially in it.
The question is, why do we need the collector-base junction? Why is it necessary?

I just keep hearing that Felix could break the Newtonian physics laws by his jump. Which laws exactly do people mean? Did he really exceed the speed of sound? Was there some physics theory that suggested human's inability to break the barrier of sound??

1 AnswerBiology9 years agoToday is the anniversary of one of the most vicious and violent attacks against a muslim...?
Marwa El-Sherbiny...an Egyptian pharmacist and Egyptian woman annd a mother who was living in Germany died in a disgraceful attack just because she was wearing the Hijab, yet I don't think that someone accused all the Germans for being racist and terrorists and a bunch of animals like what happened with the incident of Natasha Smith, the reporter who was raped a couple of days ago...
Anyway, The question is, if you could tell something to her family and child, what would you say? and what's your opinion about the widespread of Islamophobia? Do you think it exists or not? And if yes, who is blamed for it?
Side note : I totally sympathize with Natasha Smith just like Marwa El-Sherbiny.
