How to improve technical English (physics) in 4 months?

Question

IT education

There were some circumstances. Until April, I have no options to have good conversational technical English with me. Subject: physics. Needed for a scientific exhibition / conference / seminar. Grammar, spelling, blablabla - all this is not necessary at all. You need to speak normally and clearly (the accent is also not important).
Suggest ways to solve the problem and tools.
I think this way: audio courses on the phone / headphones, video courses at home, a bunch of text in the kindle5 reader (with a translator). + Skype chat with someone who speaks English.
Recommend specific audio / video courses, articles / magazines / books for the reader, and generally share the experience of quickly mastering a small specialized segment of the language.

Answer 1

Take a physics course at khanacademy.org

Answer 2

How can you speak without knowing grammar? And, probably, like this: “No, you don’t understand me. I have been studying this photon stubbornly since 2000” =) I will
advise my favorite site lingualeo.ru. They also have mobile apps.
There you can:
1) add to the dictionary all the physical terms that are required
2) learn the required minimum grammar for normal speech
3) train words (memorization, listening and others)
You can buy a paid account to access all courses, but, what’s good, You can work there for free.

Answer 3

Read a couple of dozen articles from the British and Americans (it is better not to read from the Chinese) on the relevant topics and discuss with your supervisor, or just with a well-speaking acquaintance.
If editorials are too steep and you need high school physics, read the original Feynman Lectures.
Listening to words on the road from the player, in my opinion, is absolutely useless, if you don’t purposefully concentrate, then the brain simply turns off the processing of sound information, you just need to communicate.
