I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Letters to the Editor — June 13, 2021” Fix mask hysteriaKarol Markowicz succinctly captures the irrationality that has large numbers of people who are vaccinated against COVID still behave as though they are in mortal danger of contracting the disease every time they step into a public place (“Please, NY: Unmask,” June 9). In my…
“#What Are the Odds of Nobita’s Terrible Test Scores in Doraemon?” June 2nd is “Guutara Kansha no Hi” (“Thank Goodness for Slackers Day”), a fictional holiday from the Doraemon children’s manga by Fujiko F. Fujio that honors the joys of being a lazy good-for-nothing, and to celebrate the occasion Rikao Yanagita, a lecturer at…
“#Oregon promotes teacher program to subtract ‘racism in mathematics’” The Oregon Department of Education (ODE) recently encouraged teachers to register for training that encourages “ethnomathematics” and argues, among other things, that White supremacy manifests itself in the focus on finding the right answer. An ODE newsletter sent last week advertises a Feb. 21 “Pathway to…
“#Maths has revealed how the COVID-19 vaccine should be distributed” How well we distribute and administer a COVID-19 vaccine will have massive health, social, and economic ramifications. So attention is turning to vaccine supply chains and logistics. Designing how best to vaccinate billions of people worldwide is complex. This is particularly so for large countries,…
“#A new method for directed networks could help multiple levels of science” Global book translation network plotted with new trophic level vertically. Edges and edge weights represent the number of books translated from source into target language. Upward arrows are plotted green and downward arrows red. Node size is proportional to the sum of incoming…
“#New mathematical method shows how climate change led to fall of ancient civilization” This figure shows the settlements of the Indus Valley Civilization during different phases of its evolution. RIT Assistant Professor Nishant Malik developed a mathematical method that shows climate change likely caused the rise and fall of the ancient civilization. Credit: Rochester Institute…
“#The mathematical magic of bending grids” A curvy shape created from a flat grid. Credit: Vienna University of Technology, TU Vienna An amazing construction method for curved structures was developed at TU Wien (Vienna): With a flick of the wrist, flat grids become a 3-D shape. How can you turn something flat into something three-dimensional?…
“#Mathematicians unravel a thread of string theory” Example of a cross-section of K3 surface in 3-space, similar to a model Utah State University and University of Missouri-St. Louis mathematicians used to examine string dualities between F-theory and heterotic theory in eight dimensions. Credit: USU Simply put, string theory is a proposed method of explaining everything….
“#Researchers nearly allowed the solution to a math riddle to slip away” Credit: CC0 Public Domain Computer science researchers from the University of Copenhagen and the Technical University of Denmark (DTU) thought that they were five years away from solving a math riddle from the 1980’s. In reality, and without knowing, they had nearly cracked…
“#Network of sounds: New research reveals the magic secret of human networks” Credit: CC0 Public Domain A group of Israeli researchers recruited 16 violinists to study the behavior of a human network and find out what sets it apart from other networks, such as animals, computers, and other objects. The results combine science and esthetics,…
