Love Know your teacher!1. Russian (please informme of any typos).2. In the U.S.; teach Physicsand Math since 2007,Please, ignoreincludingthe way I soundBU PY105/106 courses.(accent, s.xyz/evvv.html

Looking for a studentto be hired for helpwith bringing theequipment in and outthe class room. Classtime included.

Please, read the disclaimerToo fast , very fast,Some topics rushed(12)Grammar,Handwriting is hardto understand,Messy handwriting(17)Difficult tounderstand as aresult of his accent,Doesn’t speak clearlyHard to understand(15)

LectureMCQ L1Question 2 “I am very good at physics”On a scale from 1(strongly disagree) to9 (strongly agree) howwould you assess thefollowing statement?“I am very goodat physics! (I think)”or select 0 if you arenot sure.1. Strongly disagree(meaning, “I am veryBAD at physics”)2.3.4.5. More or less agree(meaning, “I’m OK”)6.7.8.9. Strongly agree (meaning,“I am very GOOD atphysics”)

Unit sections:begin TODAY. A usual labroom is SCI 134, butsometime labs may be held indifferent rooms.Today all you need is theaccess to the Internet.IL1, and IL11 are mandatory; they requirean access to the Internet.From the other 9 IL (from IL2 to IL 10)any 7 must be finished to graduate fromthe course.From the other 9 IL (from IL2 to IL 10) 8 best grades will beaccounted toward the final grade.

Investigative laboratoriesPlease, do not usecomputers for anythingnot related to your study,Thank you.

Lectures: up to 5 lectures are allowed to bemissed due to unforeseen circumstances.IL2 – IL9: 8 best grades will be used.Homework: To pass the course a studentmust have at least 50% of the maximumhomework grade.All homework assignments will be accountedfor the final grade.

Don’t READ Some helpful questions for solving physics problemsThis slide!(page # 12)1. What objects are involved? What processes are happening tothem? (use your imagination - make a picture showing the objectsand the processes they are involved into)2. What properties of the objects and the processes might beimportant?3. What physical quantities should be used for describing thoseproperties, what connections might be important?5. What laws or definitions should be used to describe importantconnections mathematically?6. How can I solve my equations mathematically?8. Does it make a sense?9. Could I solve a similar problem again? How much time would ittake? Who could help me (if I need it)?More at: http://www.Cognisity.How/2018/02/Algorithm.html

Not everyone canhandle a dozen ofballs, but everyonecan handle one ortwo. Not everyonecan become a Nobellaureate in physics,but everyone can learn how to solve typicalphysics problems (it's not genetic, it’s askill); there is a strategy for that.Alexander Koblikov
