Let a hundred flowers bloom; let a hundred schools of thought contend
Economics over the years has become more and more abstract and divorced from events in the real world. Economists, by and large, do not study the workings of the actual economic system.

They’d sit in their studies and say to themselv...
متن کاملVerifying one hundred prisoners and a lightbulb
This is a case-study in knowledge representation and dynamic epistemic protocol verification. We analyze the ‘one hundred prisoners and a lightbulb’ puzzle. In this puzzle it is relevant what the agents (prisoners) know, how their knowledge changes due to observations, and how they affect the state of the world by changing facts, i.e., by their actions. These actions depend on the history of pr...
متن کاملA Hundred Years of Larmor Formula
Sir Joseph LARMOR showed in 1897 that an oscillating electric charge emits radiation energy proportional to (acceleration) 2. At first sight,the result appears to be valid for arbitrary accelerations. But, perpetual uniform acceleration has been a case of nagging doubts, as radiation reaction vanishes and the equivalence principle, as also conformal symmetry of Maxwell equations each require ni...

Looking into the cavities of the human body by means of devices, without having to make an incision in the skin, has always been the dream of surgeons. The quest to light up these dark spaces was resolved for the first time in 1886, with the advent of the first cystoscope fitted with an incandescent bulb, designed by Leiter and Nitze in Germany. In 1910, it was improved on by the Swedish physic...
