Hi,<br /><br />I'm applying for a Ph.D program in physics.<br />The document that I uploaded is a part of my personal statement.<br />People usually think physics is unuseful and unnecessary in our lives. But I didn't mention this in it because I'm not writing for the public but for the faculites. So I'm claiming that device physics should be studied by physicst if we want something ground breaking result in terms of its application.&nbsp;<br /><br />I really wanted to be concise and clear. I want it to be interesting to take faculites attention a little bit.&nbsp;<br /><br />Thank you!!
