It’s mainly about avoiding unnecessary contamination while moving around the sterile field. When we’re scrubbed and gowned, the front of the gown is considered sterile, while the back isn’t. So we’re trained to be very deliberate about how we turn, move and pass around other sterile staff or equipment. Walking backwards in situations like this isn’t a universal rule, but it can simply be part of maintaining awareness of the sterile field. After a while, those movements become second nature.
@IfindRetards Imagine being this emotionally invested in how complete strangers choose to spend their own time and money. They queued for a phone. You queued up online to call them losers. I’m not sure you’ve established the intellectual superiority you think you have. 😂
They’re harming absolutely no one. I wouldn’t queue for hours for a phone either, but imagine being so damn arrogant that you think your priorities are the universal standard everyone else has to live by. Their time, their money, their choice. Mocking complete strangers for enjoying something you personally wouldn’t do doesn’t make you smarter than them. It just makes you an asshole with a superiority complex.
In reality, Earth wouldn’t remain intact like this. As it approached the black hole, the difference in gravitational pull between the near and far sides would generate enormous tidal forces, progressively deforming and eventually tearing the planet apart. The debris would be stretched into streams of material, some potentially forming a hot accretion flow before falling inward. Exactly where this disruption occurs would depend on the mass of the black hole.
I’m genuinely concerned about the rise of Muslim extremism. What scares me is seeing people embrace radical views and show hostility towards the very society they live in, while at the same time benefiting from welfare and services funded by hardworking taxpayers. And when it gets to the point where someone is actually planning to harm innocent people, that’s something we absolutely should be talking about.
@MasterMaliq Not all Muslims are terrorists, but there are extremists who have a strong hatred towards us, especially Westerners and white people like myself. They hold radical views and, in some cases, openly promote hatred and violence.
A positive screening test doesn’t necessarily mean HIV. Fourth-generation tests are highly sensitive, so false-reactive results can occur, including during pregnancy.
If the screen is reactive but the antibody differentiation test is negative, the next step is an HIV-1 RNA NAT to distinguish a false-positive result from very early acute infection. If RNA is negative, it’s most likely a false-reactive screen; if positive, it indicates acute HIV infection and requires prompt management.
@honeeybuch “The most peaceful religion in the world.” Sure. And North Korea is the Democratic People’s Republic. Putting it in the name doesn’t make it true.
This is highly suggestive of ichthyosis hystrix, Curth-Macklin type. The lifelong progressive course, widespread spiny hyperkeratosis and marked palmoplantar keratoderma fit the phenotype well, particularly with a positive family history. It’s a rare inherited disorder of keratinization classically associated with pathogenic variants in KRT1.
It really depends on the black hole. With a smaller one, the tidal forces would probably spaghettify you before or around the event horizon. With a supermassive black hole, though, you could actually cross the event horizon without noticing anything dramatic at first. There’s no wall or surface to hit.
The bad news is that once you’re in, you’re not coming back out. And what actually happens deep inside? That’s where our current physics basically says, “Yeah… we need a better theory for this part.”
@IhabFathiSulima The “machine-oil” fluid is the giveaway here. In a suprasellar cystic lesion like this, especially with calcification, I’d be thinking adamantinomatous craniopharyngioma. That thick golden-brown fluid is classically associated with cholesterol-rich cyst contents.
@cnni Well, CNN… actions have consequences. Can’t say I’m shedding any tears over this one.
Looks like the front-row access just became a front-gate experience. Enjoy the fresh air.
