What test should I use to compare two or three means, if data is not normally distributed but sample size is > 30 in each group?

I personally feel this as a most confusing question. As per my understanding, if sample size is > 30, and sample is skewed, we can still use paramteric approach, as it will follow Z...

Could anyone tell me what is the range of submillimeter wave?

There is confusion regarding the submillimeter-wave range. Many papers specify its range from 300GHz but some also consider its range from 100GHz. If I design an antenna on 122ghz what would I...

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...
