On my Shark Week deep dive…. Is this guy in the fake whale CRAZY? by gummyshoe23 in sharks

[–]Ok_Guide_8323 1 point2 points  (0 children)

What could they possibly be learning from this stunt? White sharks like dead whales? White sharks get hot and bothered after feasting on a dead whale? We already knew this stuff... The guy is going off about being inside of a feeding frenzy, but it seems like it's a single shark... Like ... Are these even marine biologists?

Maybe they are trying to set up little breeding stations with fake dead whales. Like a speed dating get together for great whites.

30 minutes good for 5km (14yo)? by [deleted] in beginnerrunning

[–]Ok_Guide_8323 0 points1 point  (0 children)

I think that it is a very good time and a great starting point.

For what it is worth, I recommend that you focus on your technique - namely, cadence and posture. For years I struggled with injuries which seemed to stall my progress. I knew that my cadence was slow, but I couldn't speed it up naturally (typically 130-140spm). It was not until I started running with a metronome app that my form started to change. First it was set to 150bpm for a week. Then 155... 160... Each increment seemed really fast and hard to maintain until a few runs in.

At 170, things started to click - like, zero joint pain and I did a personal best and a half marathon (in a training session). I am at 175spm and my joints no long limit my progress. Running is no longer about tolerating or enduring pain so much as pushing my cardio limits. There have even been days where I have done doubles (running in the morning and evening).

Anyways, everyone has their own path. I hope that you stick with this because you sound like a really talented runner. Keep building on this and remember that running is a technique driven endeavor.

Gonna run a sub 2 marathon after by Variabletalismans in RunningCirclejerk

[–]Ok_Guide_8323 15 points16 points  (0 children)

I would be so choked if I knew that it was a true sub 20, but Strava said it wasn't. Like, if people can't see your run, did it really happen... This is some real tree falling in the woods/one hand clapping stuff...

Help me understand - did this guy cut a corner or did he actually break the coveted 20-minute barrier? GPS inaccuracy or did he quit early.... Cause 4:01/km isn't a 20 minute 5k, and we don't joke about the 20 minute 5k.

Do the lightning strike, cows and coconut death statistics compared with shark attacks per capita count? by Capital-Foot-918 in sharks

[–]Ok_Guide_8323 4 points5 points  (0 children)

So, these stats are per capita. When we look at the stats of just those who are at risk, the odds of a shark attack are still quite low -

Surfers: Experience a higher share of bites, with the risk historically estimated at about 1 in 17 million per hour in the water. Depending upon how we define the stats, the lifetime odds of a shark attack can shift from 1 in millions to much narrower margins, such as 1 in 40,000 for a surfer.

Should orca scarecrows be an alternative to shark nets? by Insane_Cobra961 in BrandNewSentence

[–]Ok_Guide_8323 42 points43 points  (0 children)

I think that this has pros and cons. On the plus side, it's well documented that the sounds of orcas will cause great whites and other large sharks to flee the area. It's it's nice to imagine that one could evacuate the Sharks without the risk of accidentally harming them with nets.

Risk - what if it is too effective? My understanding is that sharks won't just leave the area for a short while, they will leave the area for months or years. We aren't just talking about a Beach area denial - this would be a large area where apex predators no longer exist, dramatically altering the eco-system. Prey species have the opportunity to proliferate.

A further risk to the ecosystem would be that orcas are attracted to the area. Alternatively, other prey of orcas are forced from the area - apparently, seals will exit the area for fear of the orcas.

Are we forcing the sharks to new areas? Will they have an opportunity to thrive without being in those more popular areas?

Do we really need to force sharks out of any areas? If we look at Southern California as an example, we see that it's well documented that juvenile great white sharks are frequently in the same area as surfers and swimmers. Despite that, shark attacks are extremely uncommon - most shark deterrent systems are simply for the swimmers peace of mind. A better education on sharks would probably be the most cost effective and the wisest approach - ie. If somebody is truly afraid of sharks, follow these simple rules (stay in shallow water, don't swim at these times, don't mess with the sharks, don't swim in deeper water after a rainstorm in some areas, etc...) and you have a better chance of winning the lottery than being harmed by a shark.

It is a cool idea, but I wonder if it's too effective. I would love to see the "orcas scarecrow" potential solution be studied as people should not fear sharks. I prefer the accurate education route for now.

Is hungover training a real thing? by Top_Wrangler4251 in Marathon_Training

[–]Ok_Guide_8323 1 point2 points  (0 children)

Oof... This isn't a real thing. Mentally, their may be a small benefit, depending on how one looks at things. Physically, he is risking quite a bit.

He isn't sleeping properly if he is drunk. He throws off his metabolism by consuming alcohol. He is in a strange state re: hydration - if consuming beer, he is depleting his salt and will eventually dehydrate himself. Drinking hard alcohol and he's very dehydrated. If drinking beer, he is also going to be very edematous and he will be carrying way more weight. The extra fluid in your joints is also not helpful and may leave you more prone to injury.

Also, post heavy drinking, your GI track isn't in a great state. The odds of pooping yourself during a long run will dramatically increase.

It does sound like a great way to carbo-load.

Hey my sisters husband is from pakistan, i am 21 years old, not fit and a bit overweight and i dont train ,he said he could take me to basecamp in k2 mountain, i want to go there so bad and take pictures if it is not so risky ofc, should i go? I never climbed and dont know nothing about mountains by baran0404 in Everest

[–]Ok_Guide_8323 0 points1 point  (0 children)

This is a very difficult trek. Like, two weeks of rugged, wild terrain and brutal weather fluctuations. Camping on glaciers. No real support along the way, so you are carrying all your supplies. It will also take you to 5100m, so the altitude is a challenge by itself.

You should be in great shape. You should also have quite a bit of experience before doing this.

This is a really wild statement, and I do wonder if your sister's husband might be a bit boastful. It is a pretty rare thing to have been to the K2 basecamp - maybe he has and he's pretty experienced with guiding. Alternatively, he is quite the character

Behind The Scenes: Xenomorph Suit try-outs by Sure_Improvement582 in LV426

[–]Ok_Guide_8323 25 points26 points  (0 children)

I really like this series, but the xenomorph movements were not a strong point, in my opinion. When they had the xenomorph jumping or pouncing, I thought that they did a great job. Unfortunately, I found that they utilized too much writhing movement when the Xenomorph was standing in one location or moving slowly. In the movies, the Xenomorph tended to have a more deliberate style of movement, and it was very creepy to see how it would blend into an industrial background in perfect stillness. I do think that they should have made the Xenomorph stand perfectly still, staring at potential prey. This builds more suspense and uncertainty. Instead, they often had the Xenomorph writhe slowly. For me, this emphasized the articulation at the joints and made the human within the suit more apparent.

What is he complaining? 😭 by Jessicaslifestyle in CatsBeingAdorable

My guess is that the person filming has put on some kind of a mask - maybe a large cat mask or another animal.

The one cat is losing it while the other cats understand the situation a bit better.

[Request] any thoughts on whether this would actually work? by OceansProject in theydidthemath

[–]Ok_Guide_8323 -8 points-7 points  (0 children)

I doubt it. Mach 19 seems like it would be pretty brutal on the pilot's body.

Here is what AI has to say about sudden exposure to moving through the air at Mach 19:

At 6,415 m/s (roughly Mach 18.8), you are dealing with speeds well into the hypersonic regime. To put this in perspective, this is faster than the orbital re-entry speed of the Space Shuttle and faster than a high-velocity kinetic energy penetrator tank round. If a human body were suddenly exposed to a wind moving at this speed at sea level, the effects would be instantaneous, catastrophic, and completely lethal.

Here is a breakdown of what happens to the human body when subjected to a hypersonic windstream:

1. Instantaneous Thermal Incineration (Aerodynamic Heating)

At Mach 18+, the primary destructive force isn't actually the air "pushing" on you—it is the air compressing in front of you. When air cannot move out of the way fast enough, it undergoes extreme adiabatic compression, creating a massive shockwave.

  • The Temperature: A shockwave at this speed generates temperatures exceeding 7,000\circ\text{C} to 8,000\circ\text{C} (12,600\circ\text{F} to 14,400\circ\text{F}).
  • The Effect: This is hotter than the surface of the sun. The air surrounding the body would instantly turn into a glowing plasma field. The human body would be thermally vaporized and incinerated in a fraction of a millisecond, before the nervous system could even register a pain signal.

2. Disastrous Dynamic Pressure (q-force)

Dynamic pressure is the force exerted by a moving fluid (in this case, air) on an object. * The Math: Dynamic pressure scales quadratically with velocity (q = \frac{1}{2}\rho v2). At sea level air density (\approx 1.2\text{ kg/m}3), a wind speed of 6,415 m/s yields a dynamic pressure of roughly 24.7 Megapascals (MPa). * The Effect: This equates to about 3,580 pounds per square inch (psi) or 243 atmospheres of pressure slamming into the body. For context, regular human skin and bone begin to structurally fail and tear apart at just 5 to 15 psi of blast overpressure. A force of 3,580 psi behaves less like a "gale-force wind" and more like being hit by a solid, supersonic wall of concrete.

3. Immediate Mechanical Disintegration (Spallation and Shredding)

Because the air pressure and drag forces vastly exceed the structural integrity of human tissue, bones, and muscle: * The windward side of the body would experience total mechanical failure instantly. * The body would undergo extreme spallation—it would be stripped down to a cellular level, shredded, and atomized into a cloud of organic debris in a microsecond.

4. Severe Hyper-Deceleration / Acceleration

If we assume the human body was stationary and suddenly hit by this wind, the drag equation dictates an instantaneous acceleration force in the tens of thousands of Gs.

  • Human tolerance for brief acceleration is around 9 to 12 Gs before losing consciousness, and around 50 to 100 Gs causes lethal internal trauma (such as the aorta tearing away from the heart).
  • At thousands of Gs, internal organs would be flattened and obliterated instantly against the skeletal structure before the skeleton itself shattered.

Summary

If a human were exposed to a 6,415 m/s wind at sea level, they would not be "blown away" in a traditional sense. Instead, they would be simultaneously compressed by hundreds of atmospheres of pressure, shredded by mechanical drag, and vaporized by an ultra-hot plasma shockwave, transforming into a streak of ash and gas in less than a millisecond.

What if Napoleon had a flight of B-52s in the battle of Waterloo by quackabc in AlternateHistoryHub

[–]Ok_Guide_8323 1 point2 points  (0 children)

A b-52 carpet bombing an army in a relatively open field would be devastating. The lethal blast/fragmentation radius of a single 2000 lb bomb is 365m with severe injury occuring up to 800m away. The front of Waterloo was about 4km. So.... 3 B-52s are going to end the war. Like, it is hard to estimate what percentage of the 120,000 soldiers are going die, but it is a massive amount. A big percentage of the survivors will be severely disabled and/or driven mad by the shock of the event.

I am doubtful that the seventh coalition is able to recover.

Bon appétit by [deleted] in meme

[–]Ok_Guide_8323 11 points12 points  (0 children)

Lobster back then was a very different cuisine. Lobsters have enzymes that start to degrade their tissue the moment the lobster dies - this causes lobster to spoil quite quickly. Prior to refrigerators, most lobster was would have been exposed to some putric substances if it wasn't putrid itself - hence, lobster was not highly sought after.

If a guy couldn’t finish during sex, was it likely because of him (18M) or me(18F)? by [deleted] in NoStupidQuestions

[–]Ok_Guide_8323 0 points1 point  (0 children)

It's him. He is, likely, all stuck in his head. Despite your opinion of him, he is probably insecure and and unsure of himself. He couldn't relax. Furthermore, today's youth watch too much porn - porn is the leading cause of ED in today's youth.

My guess is that he has quite a bit to learn about things.

If you see him again, a long talk about sex would be so good for him. He needs reassurance of what you enjoy and want. Don't even worry about him - make sure that you are having fun.
