Consider the following belief
A human can survive if they don't drink water for 1000 days
We knew from biology that this is practically improbable as there are very few people who can survive for 18 days without water (Andreas Mihavecz in 1979).
However, there are also beliefs that are unr...
I found this image on Facebook referring to the Portal videogame. But I wonder... What would really happen if this was in real life, supposing the portal was a wormhole?

What is the exact link between spinors and the Grassman algebra? I'm pretty sure there's one, based on the following :
The Berezin integral in path integrals is done over the Grassman algebra of $\Bbb C$
There's a mapping from the tangent bundle of a supermanifold (which is locally $\Bbb R^n \...
A physician, medical practitioner, medical doctor, or simply doctor is a professional who practises medicine, which is concerned with promoting, maintaining, or restoring health through the study, diagnosis, and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice.

Feminist technoscience is a transdisciplinary field which emerged out of decades of feminist critique on the way gender and other identity markers are entangled in the combined fields of science and technology. The term technoscience, especially in regard to the field of feminist technoscience studies seeks to remove the distinction between scientific research and development with applied applications of technology while assuming science is entwined with the common interests of society. As a result, science is suggested to be held to the same level of political and ethical accountability as the...
given a metric
$$\gamma_{ij}=\delta_{ij} +kx_{i}x_{j}/(1-kx_{k}x^{k})).$$
Einstein summation convention is implied because of the upper and lower $k$ indices. Do I sum over the $i$'s and $j$'s as well? I get nuisance cross terms if I do.
Hauntology (a portmanteau of haunting and ontology) is a concept coined by philosopher Jacques Derrida in his 1993 book Spectres of Marx. The term refers to the situation of temporal, historical, and ontological disjunction in which the apparent presence of being is replaced by an absent or deferred non-origin, represented by "the figure of the ghost as that which is neither present, nor absent, neither dead nor alive." The concept of hauntology is closely related to Derrida's deconstruction of Western philosophy's logocentrism, which results in the claim that any attempt to isolate the origin...
