TikTok tests 60-minute video uploads as it continues to take on YouTube

Posted by in category: education

TikTok is testing the ability for users to upload 60-minute videos, the company confirmed to TechCrunch on Thursday. The feature is available to a limited group of users in select markets, and TikTok says it doesn’t have any immediate plans to make the feature available widely.

The feature, which was first spotted by social media consultant Matt Navarra, marks a shift from TikTok’s original format. The app allowed users to upload 15-second videos at launch, but TikTok has been increasing that limit over the past few years. While the company rose to popularity for its short-form video format, it has slowly been embracing long-form content to take on one of its biggest competitors: YouTube.

TikTok says that while creators can weave multipart stories together by telling viewers to go to part two or more of a story, it often hears from creators who want more time for things like cooking demos, beauty tutorials, educational lesson plans, comedic sketches and more.

Intense quantum light generates ‘weird’ electron behavior

Posted by in category: futurism

Photon-number distributions of various light sources have been studied extensively, but little is known about the statistical distribution of electrons emitted under the effect of intense quantum light.

However, researchers at the Max Planck Institute for the Science of Light (MPL) and Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have made a discovery that highlights this phenomenon.

Published in the journal Nature Physics, the study led by Prof. Maria Chekhova at MPL and Prof. Peter Hommelhoff at FAU reveals extreme and highly unusual statistical events in electron-number distributions obtained when nanometer-sized metal needle tips are illuminated with ultrashort pulses of bright quantum light.

A New Dimension of Quantum Materials: Topological Phonons Discovered in Crystal Lattices

Posted by in categories: mathematics, particle physics, quantum physics, space

An international research team has shown that phonons, the quantum particles behind material vibrations, can be classified using topology, much like electronic bands in materials. This breakthrough could lead to the development of new materials with unique thermal, electrical, and mechanical properties, enhancing our understanding and manipulation of solid-state physics.

An international group of researchers has found that quantum particles, which play a key role in the vibrations of materials affecting their stability and other characteristics, can be classified through topology. Known as phonons, these particles represent the collective vibrational patterns of atoms within a crystal structure. They create disturbances that spread like waves to nearby atoms. Phonons are crucial for several properties of solids, such as thermal and electrical conductivity, neutron scattering, and quantum states including charge density waves and superconductivity.

The spectrum of phonons—essentially the energy as a function of momentum—and their wave functions, which represent their probability distribution in real space, can be computed using ab initio first principle codes. However, these calculations have so far lacked a unifying principle. For the quantum behavior of electrons, topology—a branch of mathematics—has successfully classified the electronic bands in materials. This classification shows that materials, which might seem different, are actually very similar.

A History of Western Philosophy
