Dig into the science of radiosurgery: a procedure that uses light beams of radiation to target tumors, without making a single incision. Every year, tens of thousands of people have brain surgery without a single incision: there s no scalpel, no operating table, and the patient loses no blood. Instead, this procedure uses a machine that emits invisible beams of light at a precise target inside the brain. So how exactly does this treatment work? And what does it do to the tumors it targets? Hyunsoo No explains radiosurgery. Lesson by Hyunsoo Joshua No, directed by Hype CG

How lucky we are that we are at a point that is so much crucial for the mankind. Today the innovations and technology are going to propel and decide where we stand in the centuries to come. Just imagine how powerful humans will be when we master the things at which we are novice yet. Truly we have a promising future ahead.

Hmm, minor correction:
At 2: 53, there shouldn't be a + and - signs near the particles. They are radicals, which means they have unpaired electrons and are very chemically active because of that.

I still don t really understand how surrounding tissue isn t irradiated - I imagine it would work more like a drill: irradiating tissues from the outermost layers all the way down to the tumor

When TEDed can explain your chosen subject of study better than your lecturers.
Wow, my university needs to simplify things haha. This makes my future career seem so much simpler! Haha

Do we need to lose any blood during brain surgery?
Scientists: No!
Today's educator: Didn't I forbade you to call me when I'm eating.
Scientists: visible confusion

I just wanted to let you know the things you do for us do not go unnoticed. I appreciate your dedication and service, and I know others do too!
