A lot of us were truly surprised years ago when some of the #AngryBirds against #StringTheory came out with statements to the effect that for decades stringers had been *stealing their lunch money* like it had been the only game in town. Many of us had to say Fark ! Where were we ? We missed it !
But now we have the #Internet and #SocialMedia and #Researchers of course will abide dirty laundry in the name of #Science. Come for the shitshow,stay for the science. AMA at the end. BYOB

📣 PhD student position 📣

Join our institute in Potsdam, Germany! We offer an ERC-funded PhD student positions at the @mpi_grav in Potsdam.

We are particularly interested in hiring creative, proactive and motivated candidates who flourish at working in a vibrant, interdisciplinary and synergistic group. Successful candidates will join the research group “Symmetries in Gravity and Amplitudes” with the Quantum Gravity and Unified Theories division.

The PhD research will focus on mathematical structures of scattering amplitudes, more specifically amplitudes associated with Riemann surfaces as they appear in string theory.

The successful applicant will conduct their research projects at the AEI in Potsdam, and they will have to enrol and receive their PhD degree from the Humboldt University in Berlin. The expected duration of the PhD is three to four years. Applicants are required to have a Master degree by the start of the PhD program.

@tg9541 OK, I have read Stuart Kauffman’s book “At Home in the Universe”, and am familiar with the concept of ‘emergence’, as well as the philosophical conflict concerning #reductionism. But I am also skeptical of #math substituting for #science - as in #StringTheory.

To get to the point of this limited toot, I recall from long ago the discovery (by radiolabeling) that “biological structures are replaced every 8 weeks”, but more recent experiments refuted its generality.
