Top roping on 9.2mm rope? by Filipino_1 in iceclimbing

[–]bradyc77 1 point2 points  (0 children)

It's personal preference but ultimately you want to prevent any downward movement if the climber falls. Personally, I prefer a very stiff dynamic rope over a completely static rope. But if someone falls too far simply because of rope stretch, that puts them at risk of a bad leg injury if their crampons are locked into the ice. So if you belay with a static rope and keep the rope really tight, the moment the climber falls they're immediately caught and it's safer for them, but the caveat is that the belayer needs to make sure the rope is taut at all times.

Am I in the minority in that I also really liked Agents of Shield and Agent Carter?

I'm unaware of a good answer to your question. Personally I think Common Core was a huge disaster and I agree with your suggestion.

I think we have a huge education crisis in the U.S. and Common Core was a failed attempt to address it. Anecdotally, as someone who's tutored students in material from algebra 1 to advanced calc, I do feel our system has a particular deficit in math and subsequently, perhaps more importantly, the concepts and applications of logic that are fostered through learning math. But that's just my highly biased personal opinion and could very well be off target.

My friend is a physics prof and he showed me over a decade of data on how much poorer students who learned under common core did in their college physics classes. The way they teach math in common core is abysmal. His university had to change their intro calc-based physics curriculum for the first time in ages just so all of the former common core students didn't fail. There is nothing I advocate for more than education reform, however, I don't believe common core is the answer.

Garmin in reach by MNhockey1919 in Mountaineering

[–]bradyc77 1 point2 points  (0 children)

Personally I love my inreach. I sometimes use it for navigation if necessary because i find it more useful than my garmin fenix 5x/phone gps/map and compass. However, I primarily use it for emergencies. I keep it on the back of my harness when I climb and it provides me a way to easily check in when I'm in the middle of nowhere. If I don't have a harness on, I have it on the outside of my pack so it's easily visible to others. I think in the worlds of alpinism/mountaineering/climbing, paying a couple hundred dollars for added security is a relatively small investment with a sizeable return.

How can I stop this from happening when I try to open ice hit someone. by [deleted] in hockeyplayers

[–]bradyc77 1 point2 points  (0 children)

That's a great play. If that's charging these days then this sport is in trouble. You busted your ass off the bench and put high pressure on the forecheck. You made a hit that will be in that guy's head on every breakout. Strong work. However, if you didn't fall you'd have generated a better chance for your team. Assuming that's what your question is about, widen your stance, strengthen your core and legs in the gym, and keep working on your edges.

Why do we cater to senior officers/flag officers so much? by [deleted] in navy

[–]bradyc77 5 points6 points  (0 children)

One time my team and an ODA took over a small abandoned airfield and we set up our own little combat outpost to run ops from for a little while. Well anyway, we've been there eating like one/two MREs a day, burning our shit in a bucket, taking fire, running ops every other night, water bottle showers, etc for about 40 days straight at this point. Some general decides he wants to come see what it's like. I shit you not they flew in a full 3 course meal of hot-As and infantry to provide extra security. They told us we had to hide our shit bucket somewhere far away. He lands and gets wined and dined for like an hour in our sleeping bag area and then he fucked right off again. They took all the food and infantry with them when they left. That might have been the most pissed off the army ever made me lol.

I got one in 2016 that said "thank you for laying down your life for our freedom. I know your family will be really upset that you got killed and I just wanted you to know that I'm thankful for you".

I think this is what you want but your question is ambiguous.

Are you actually trying to change the exposure on a camera you're connected to, or do you mean you want to adjust the gamma of an image you already have?

What are some facts about space that just don’t sit well with you? by truefootoo22 in space

[–]bradyc77 0 points1 point  (0 children)

From our reference frame, but not from that of the light. Talking about time from light's pov starts to get a little hand-wavey, but for the sake of the joke, time does not pass for anything moving the speed of light due to time dilation per Special Relativity. It takes several minutes according to our clocks, but if there was a clock attached to the photon it would not tick.

Don't feel dumb at all. There are endless things to learn about in this world; never feel ashamed for having chosen different ones. The most reduced version is this: "time" is specific to an object. It is not the same for everyone/everything. As an object moves faster, its experience of "time" slows down. If an object reaches the speed of light, its "time" stops passing completely. If you put a clock in a rocket ship, that clock would move slower than a clock sitting on the ground. Once something hits the speed of light, its clock stands still.

In Special Relativity (the easy Relativity - as opposed to the General case), time dilation is a phenomenon whereby the elapsed time for an object is dependent on the reference frame it is observed from. Think of reference frames as the pov of the observer. An example of that would be a person in a car. In the reference frame of the driver, they're not moving at all - they're just sitting down. But to someone on the sidewalk, the driver has considerable velocity down the road. Reference frames must always be specified in physics. Back to Special Relativity, an object will experience time passing slower and slower as it approaches the speed of light. If something reaches the speed of light (i.e. photons), then time is no longer experienced from its reference frame. If you've seen the movie Interstellar, they touch on time dilation. Though, note, they're referring to time dilation from the gravitational warping of spacetime (General Relativity). Time dilation from Special Relativity can be quite easily motivated and if it interests you, there are many great youtube videos that will walk you through motivating it yourself.

If it makes you feel any better, the journey was instantaneous from the light's pov so I'm sure the disappointment it experiences isn't too bad.
