Everyone is already familiar with the real-life applications of gravity. Not only do we feel its effects every day, but also we are provided enough information from mass media. Gravity allows to keep our feet on the ground. Without gravity, we would simply float off into the atmosphere. Gravity is an essential force in the… Continue reading What is gravitational lensing? – Jarvis Blog

definition and the ways of calculation – Jarvis Blog
A common concept in physics, waves are described as disturbances that transmit energy through matters and space. Sometimes, they are associated with mass transport, sometimes, they are not. Waves are reported, in physics, at a fixed point, and consist of oscitations or vibrations of a physical field or medium. In physics, there are known two… Continue reading definition and the ways of calculation – Jarvis Blog
Mathematicians Identify Threshold at Which Shapes Give Way
For a long time, mathematicians thought that sharp folds were the only way to have both characteristics at once: a crumpled shape with lengths preserved. “If you allow corners to happen, then the problem is much easier,” said Tristan Buckmaster of Princeton University. But in 1954, John Nash identified a remarkably different type of isometric… Continue reading Mathematicians Identify Threshold at Which Shapes Give Way
Astronomers Find Secret Planet-Making Ingredient: Magnetic Fields
We like to think of ourselves as unique. That conceit may even be true when it comes to our cosmic neighborhood: Despite the fact that planets between the sizes of Earth and Neptune appear to be the most common in the cosmos, no such intermediate-mass planets can be found in the solar system. The problem… Continue reading Astronomers Find Secret Planet-Making Ingredient: Magnetic Fields
Finland takes leading role in the openness of academic journal pricing — Mostly Physics
Freedom of Information request by open science advocates has revealed academic journal pricing through an administrative court decision. Finland is the first country where the subscription prices paid by practically all universities and research institutions to individual publishers are made available. This strengthens the position of universities in the 2016 contract negotiations, made ever more… Continue reading Finland takes leading role in the openness of academic journal pricing — Mostly Physics
one of the oldest stars – Jarvis Blog
Stars are luminous bodies which consist of chemical reactions that generate light from its core. They are also held together by their own gravity. In the universe, there are billions of stars which are categorized accordingly to similar characteristics. The major type of stars we have are the main sequence stars, red giant stars, white… Continue reading one of the oldest stars – Jarvis Blog
We Already Know How to Stop SolarWinds-Like Hacks – Facts So Romantic
Orion, a SolarWinds product, was designed to monitor the users’ networks to make sure they were functioning properly and, ironically, kept safe.Photograph by Camilo Concha / Shutterstock Last year, hackers made headlines after they breached SolarWinds, a software company that specializes in network monitoring software. About 33,000 organizations, including the Pentagon, the U.S. State Department,… Continue reading We Already Know How to Stop SolarWinds-Like Hacks – Facts So Romantic
Our Little Life Is Rounded with Possibility – Issue 102: Hidden Truths
If you could soar high in the sky, as red kites often do in search of prey, and look down at the domain of all things known and yet to be known, you would see something very curious: a vast class of things that science has so far almost entirely neglected. These things are central… Continue reading Our Little Life Is Rounded with Possibility – Issue 102: Hidden Truths
Finland takes steps in the openness of academic journal pricing — Mostly Physics
(The title is a riff on my 2016 post announcing the efforts of Finnish open science activists to obtain pricing information through the courts.) Edit 1: I gave a comment for a Times Higher Education article on Elsevier’s negotiations. Edit 2: on Feb 2, 2018, FinELib released more details, including the level of total price… Continue reading Finland takes steps in the openness of academic journal pricing — Mostly Physics
Poem: ‘Turing and the Apple’
Edited by Dava Sobel Nothing’s wholly certain. A half apple lay beside the bed, bites taken out of it, when his corpse was found—though no one really tried to ascertain if it contained cyanide. After he had seen Snow White, off and on he would chant the haggish queen’s vile couplet. Did he dip the… Continue reading Poem: ‘Turing and the Apple’
