Radiation is something you can’t see; but it can still kill you. Better to know what you’re up against. I’ve made some videos in this playlist that go into the details of each type of nuclear…

I have some questions related to velocity and acceleration and I hope
someone give me some answers :
1- If the velocity of a particle is zero, can the particle’s acceleration
be zero? Explain.
2- If the velocity of a particle is zero, can the particle’s acceleration
be nonzero? Explain.
3- when throughing an object upward and reaches the highest point is the
acceleration zero or 10m/s^2 ?
4- If the average velocity of an object is zero in some time interval, what
can you say about the displacement of the object for that interval?
thanks in advance
Thank you for ever “professor walter lewin “
He has a wonderful book for sale on amazon.com, “For the Love of Physics”.
40:48 – 41:13. How does he get C to be 2^.5?
america’s best university = Europian highschool.
On thing I don’t understand
How do you do the dotted chalk line in one swipe!! it makes that purring
sound what sorcery is this?!?
Can life be more interesting than the first three minutes of this guy’s
explanation? I submit that it cannot. That equals sarcasm times the
velocity of boredom.
He bet a whopping nickel!
Now I know Surface Tablets didn’t exist back then, but dang I would be
writing on that thing like a madman and recording the voice session if the
professor was ok with it in case it got increasingly complex as far as
explanations go. Sitting up front, taking notes = FUN TIMES. Hope you have
caffeine readily available 🙂 Can’t wait to get back into university
studies
…the average SPEED!!!
are there any exercises, textbooks or recommended readings that go with
this course? if so what are they? and where can I get them?
thanks a lot for the excellent upload.
MUY BUENA CLASE, GRACIAS :)
I cant download them from the mit site anymore 404 page not found :)(
Dr. Lewin is such an awesome teacher, wish I could go to MIT :-/
Oh my god, Isaac Newton in minute 11:00
I’m going to study physics at the UBA (Argentina) this year, in three
months, this is an excellent material for studying, I’m really grateful to
the MIT for upload this classes. I wish I could study in the MIT with Prof.
Lewin, he’s an excelent professor.
+jesse1Deest It means to take the deriviative of, etc if you have a
function t(x)=2t^2-12t+16 where t is time and x is the position.. then you
find velocity by dx/dt=x'(t’)=v(t)=4t-12 and then the acceleration by
either d^2x/dt=dv/dt=4 .. Hope that helps :-)

You don’t necessarily learn something just because you were taught it as a
kid and got an A in your child class. Universities re-teach the same
material in a much more sophisticated and nuanced way (hopefully), and this
Prof is an excellent example of that. Education isn’t a grocery checklist,
there’s many ways to learn the same topic, and the fact that I learned some
basic physics thing as a kid doesn’t mean that it can’t be re-taught at an
advanced level at a top university.
my only wish is that these videos were in a higher resolution
McDonald’s welcomes you 😉
My only wish is to see the same video in a better quality …
I love graphs!! And I love how you use them ALL the time doc! It’s amazing
how perfectly connected you can make everything. Thanks so much
do you have any video about distinction among alpha beta, gamma ? i need
easy solution…
A question please – If a Gamma ray is simply light, how come it’s dangerous
and radioactive? Is it because it’s in the UV (or more dangerous) spectrum?
Oops! I got error messages on submitting the comment, so I tried it again.
And again. Sorry about the repeated comment!
MO, baby!
At 0:46 you say the strong force has no effect on the electrons because of
its short range. This might confuse students later on. The strong force has
no effect on electrons at all, regardless of the range, basically because
electrons are colorless.
What state are you in doc
Firstly – thank you! I’m happy to be part of that. Secondly – I know!
Something’s got to change. Over the next ten years, there’s strong pressure
on traditional universities to either offer a better product or lower their
cost. My kids are on edX and Udacity all the time.
Funny how I pay ~SGD7000 for university but YouTube (plus others like
Udacity, StackExchange etc – all free) turns out to be a better educational
resource …
yep, $14,000 per year in student loans, plus working on top of that and
more often than not I teach myself because my instructors A) are shitty, B)
are too busy or C) make me feel dumb. (not all of them, but science in
particular, yes.) Big Kudos to Doc.
