Taming Infinities - Martin Hairer (2017 Fields Medal Symposium)
Martin Hairer, Imperial College London and Fields Medal 2014
Talk start (after introductions): • Taming Infinities - Ma...
Some physical and mathematical theories have the unfortunate feature that if one takes them at face value, many quantities of interest appear to be infinite! What's worse, this doesn't just happen for some exotic theories, but in the standard theories describing some of the most fundamental aspects of nature. Various techniques, usually going under the common name of “renormalisation” have been developed over the years to address this, allowing mathematicians and physicists to tame these infinities.

Thank you.
Excellent, very clear lecture on mathematical problems in quantum field theory and few others fields of knowledge.
Thanks adding complexity to this platform with educational videos.
Excellent.
Remarkable!
At the end of the presentation, Hairer poses the problem that some parameters could not be accounted for because their value is a function of the zooming in used. However, in nature, the ultimate zooming in is the Planck scale. So the solution of the equation is more straightforward at this scale

Your theory is slightly frustrated by the fact it will be impossible ever to make any measurements at anything like that scale.

@greglejacques1094 Stupid flippant response. It would have been equally convincing if you had replied by telling me the problem with my theory is that everything is bestowed by God.
