Thirty years ago, Robin Dunbar theorized humans can maintain a friendship group of 150 people, with five intimate friendships. Despite many attempts to challenge the theory, Dunbar's Number has stood the test of time. Backed by neuroscience and statistics, Robin Dunbar explains why his theory still prevails.
A new mathematical model shows the current COVID-19 pandemic could decline during the summer months, but return in the fall, with a major resurgence next winter. The model takes into account the seasonal variations of other closely related respiratory coronaviruses. Based on other coronavirus data, the model reveals infections were ten times more common between December and April in the northern hemisphere than between July and September. Researchers emphasize this model only attempts to examine possible scenarios, as we are currently unsure how warmer temperatures will affect SARS-CoV-2.
Our knowledge of the world has a critical impact on the ability to use mathematical reasoning, even for mathematicians. Findings reveal math professionals can be duped by some aspects of their knowledge about the world and fail to solve simple fifth-grade math problems.
Fitting musicians with motion capture sensors and applying mathematical techniques, researchers discover how musicians communicate non-verbally while performing different pieces of music.
Researchers have developed a new mathematical model, which incorporates EEG data and evolutionary game theory, that bridges the gap between waves and random fluctuations in the brain.
Researchers discover children as young as 6 months old can have a sense of probability.
A new PNAS study reports it is mathematically impossible to stop the aging process in multicellular organisms.
