Kosmologický model skřípe: V růstu vesmírných struktur jsou nesrovnalosti

Standardní model Lambda-CDM sází na chladnou temnou hmotu a konvenční temnou energii. V poslední době ale přibývají problémy, s nimiž se Lambda-CDM nedovede vyrovnat, včetně potíží Sigma-8 tension. Praskliny houstnou a není jasné, jak dlouho ještě Lambda-CDM vydrží. Nejnovější analýzy vládnoucímu modelu nepomohly. Buď děláme závažné systematické chyby anebo míříme k nové fyzice. http://www.osel.cz/13855-kosmologicky-model-skripe-v-rustu-vesmirnych-struktur-jsou-nesrovnalosti.html

How Big Tech became the world’s most powerful ‘religion’ and why we need to become agnostic

Greg Epstein is the Humanist chaplain at Harvard University and at MIT, where he advises students, faculty, and staff members on ethical and existential concerns from a humanist perspective. He has served for over 20 years in elected and appointed interfaith leadership roles as an advisor for the non-religious. He himself is an atheist, agnostic, Humanist.

Tech has changed roles. It used to be a mere tool that people could use for bettering and strengthening humanity. Now, it has a

Částice popela vyřešily záhadu erupce z roku 1831, která ochladila svět

Roku 1831 se celý svět ochladil, došlo k hrozivé neúrodě, a propukly devastující hladomory. Vědce po celou tu dobu mučilo vědomí, že došlo k masivní vulkanické erupci, o které nic dalšího nevěděli. Popel z ledovcových jader prozradil, že téměř 200 let hledaným vulkánem je sopka Zavaritského na Kurilských ostrovech. http://www.osel.cz/13854-castice-popela-vyresily-zahadu-erupce-z-roku-1831-ktera-ochladila-svet.html

Apple’s Siri settlement feeds the ‘eavesdropping iPhone’ narrative

Apple, which has built its brand on data privacy, settled a class action suit this week in which the plaintiffs claimed their iPhones’ Siri voice assistant listened in on their conversations for the purpose of targeting them with ads.

The iPhone-maker has (preliminarily) agreed to pay $95 million to settle the case after five years of legal jousting. The case alleged that u

Dating Wrapped: TikTok users are crunching the numbers on their dating life

If Spotify Wrapped left you underwhelmed this year, TikTok’s “Dating Wrapped” trend is here to spice things up. 

Instead of playlists, users are serving up PowerPoint-style presentations packed with stats about their 2024 dating lives. Singles everywhere are crunching the numbers on their year of dating highs and (mostly) lows, tracking drinks, dinners, ghosting, and awkward smal

Dating Sunday 2025: The busiest day on dating apps is almost here

Dating apps are gearing up for their busiest day of the year: Dating Sunday. 

This landmark day in the dating world always lands on the first Sunday of January. The idea is that singles, back from their holiday travel and with a slate of new resolutions, will turn to dating apps with fresh eyes and open hearts.

Sure, some of this is marketing, but there are stats to back up the popularity of this day. Dating apps routinely see a surge in activity on Dating Sunday.&nb

Net neutrality never stood a chance

A federal appeals court sealed the fate of the Biden administration’s efforts to regulate internet providers on Thursday, striking down the Federal Communications Commission’s 2024 net neutrality order once and for all.

The order sought to reclassify internet service providers as common ca

Elon Musk turns Cybertruck explosion into a marketing moment

The new year started out with the worst kind of bang. In the early hours of January 1, an assailant exploded a Cybertruck in front of Trump Hotel in Las Vegas, using firework mortars and gas canisters. Seven bystanders were injured in the blast, and the driver reportedly killed himself before the explosion.

16 fascinating breakthroughs of 2024 that weren’t about AI

All the excitement around artificial intelligence can make it hard to notice all the other exciting progress lately that’s been the result of human intelligence.

Of course, it’s getting harder to say what’s not got some bit of AI or deep learning in it. AI is seeping into everything, including scientific and technological discovery, with impacts that we didn’t expect. The tendencies of generative AI to hallucinate and defy explanation are already turning out to be a powerful fuel f

‘Somewhere on Google Earth, I’m still 17’: People are treating Google’s satellite service like a photo album

When taking a trip down memory lane, some might flip through a photo album or scroll through their phone’s camera roll. But would you think to check Google Maps?

Since 2007, Google’s Street View cars have been quietly documenting neighborhoods around the world. Now, in what’s been dubbed the “Google Earth trend,” people are searching for their childhood homes on Street Views, taking screenshots, and pairing them with heartfelt memories. These images, originally snapped by Google’s

My 2025 tech resolutions: ditching X, avoiding AI, and more

So many of 2024’s tech plot twists defied predictions, but we should have seen one thing coming: The industry would once again pivot away from learning from its mistakes. And while 2025 might be better, it would be a predictable error to expect the tech companies that have profited most from the current state of affairs to change their courses.

We, however, don’t have to click “accept” or “submi

Inside Pinterest’s quest to restore internet optimism

Most social media platforms have devolved into a network of bottom-feeders and rage-baiters. Yet somehow, Pinterest has kept its joy. 

According to Sprout Social’s 2024 content strategy report, more than half of social users think of Pinterest as “more positive” than other platforms. When Bill Ready became Pinterest’s CEO in 2022, he shared his vision for a kinder, more upbeat soc

Dostupné stanovovanie tlaku v ľavej srdcovej predsieni pomôže pri liečbe zlyhania srdca

Zlyhanie srdca je vo vyspelých krajinách najčastejšou príčinou smrti. Liečba, vedená podľa tlaku krvi v ľavej predsieni srdca môže predĺžiť život ťažko chorých pacientov, ibaže v súčasnosti je dostupné len invazívne meranie, ktoré nie je jednoduché a preto nie bežne dostupné.

New rules may ban Chinese drones if approved by Trump administration

The U.S. Commerce Department said on Thursday it is considering new rules that would impose restrictions on Chinese drones that would restrict or ban them in the United States citing national security concerns.

The department said it was seeking public comments by March 4 on potential rules to safeguard the supply chain for drones, saying threats from China and Russia “may offer our adversaries the ability to remotely access and manipulate these devices, exposing sensitive U.

I’m a techie, but I’ve fallen for paper notes again

Usually I type my initial thoughts for these columns on a computer, but this week I wrote them in a paper notebook instead.

I’ve never been much of a paper person. Although I did carry around a reporter’s notebook for a newspaper job in the pre-iPhone era, I prefer to file my thoughts away in digital form, where they can be categorized, backed up online, and accessed from any device.

What to do if your manager keeps watching your Instagram Stories

There are certain social media rules we can all agree on: Ghosting a conversation is impolite, and replying “k” to a text is the equivalent of a backhand slap (violent, wrong, and rude).
