Amidst the growing frictions between the US and China, the US will gradually be reducing its presence and involvement in the Middle East. What do you think the power dynamics between the big four: Turkey, Israel, Saudi Arabia and Iran will look like as that happens?

EDIT: China is bound to be the most challenging rival the US has ever faced. That much is already acknowledged by Washington’s policy makers and the Pacific region is increasingly referred to as the theatre for the 21st century power politics. While the theme of imminent American decline has been overstated in recent years, it is also true that American relative power has been waning for some time now (for a number of reasons, as simple as transfers of technology etc.) and that the US can no longer hubristically strive to be omnipresent and omnipotent. Its most pressing issue in this century (according to realists like Mearsheimer) will be ensuring China doesn’t come to dominate the Pacific. As M himself has said: the US cannot tolerate peer competitors. (The US cannot dominate the entire world but it must ensure that no other power becomes a refional hegemon.) That, the future of oil and I’d say a certain sense of fatigue among leaders and population at large about the endless involvement in the Middle East all imply a major restructuring of American presence and involvement in the Middle East. What will that mean for the four countries I listed? (Not that Egypt and UAE are minor actors, mind you, but adding them to my question would complicate things evej further. If anyone feels like sharing his opinion on them too, I would be very enthusiastic to hear it.)

TIL Lighthouses had different techniques for rotating the light, most being too slow, making the light less visible. Augustin Fresnel proposed a mercury flotation system in 1825. Despite some lenses weighing over 6,000 lbs. the design reduced friction, increased rotation, and ultimately saved lives. uslhs.org/lens-rotation

How can someone measure/quantify friction faced by visitors on a website while performing a transaction/action

This transaction could be anything depending on a website like in my case(financial website) it could range from opening a bank account/ linking an account,etc etc. Also the problem with using common metrics bounce rate,exit rate is that it completely disregard the intention of the visitors, maybe the person is just there for explorative purpose and if he doesn't perform an action that not necessarily means it's a friction point given the intention

[Advice] If you don't have enough will-power or energy throughout the day, consider eliminating more friction from your life.

Friction is anything in your life that continues to slow you down, exhaust you, confuse you, or causes you some sort of grief or inconvenience. It's a task, an interaction, or an event that continues to show up in your life and you're all like "Ugh! This again??"

Put even more accurately, it's not the thing itself but it's your relationship with that thing. When something comes into your life regularly and you're against it / in resistance to it, then this creates friction that burns up your energy.

In this post I'll share with you how to identify friction and shift it so that you can free up some more energy to move onto bigger and better things.

Friction burns up your mental and emotional resources

So when you encounter something that causes friction, it's a tax on your energy. It leaves you depleted.

Example 1: Doing the dishes. You have to do the dishes but you dislike doing them. It's boring, tedious, and you can't get it done quickly enough.

Example 2: You live with someone with whom you have unpleasant interactions. Every time you speak - seemingly - the conversation goes in a bad direction and both of you are left feeling bitter, resentful, and misunderstood.

Example 3: Writer's block (or any type of creative blockage). You had a sparking vision for a book or song or video series or script or business that you were going to create. But whenever you attempt to do it... it just doesn't happen.

In each of these cases the common thread is that you're grinding your gears. One part of you is going THIS way, and the other part of you is going THAT way. You're physically doing the dishes but mentally waiting to get through them. You're being as polite and as calm as you can be in this interaction. You're trying to force yourself to create but something else seems to be "forcing back".

In the end, no progress is made and you're left even more depleted than before.

Dissolve the friction in order to reclaim your energy

Dissolving friction can take a handful of different forms. Here are a few:

1) Ask, what do I need to realize and accept?

What are you in denial of that you need to realize and accept? Maybe it's that this person is the way they are, and you can't change them. Maybe they'll never change. In fact maybe you're not appreciating your own contribution to the toxic nature of this relationship?

This is a very powerful practice. What needs to be finally seen and acknowledged? Something about the past? The present? Wha

Writing Prompt Wednesday #238, 5/5 - Science Friction

Greetings, Huntsmen, Huntresses, and gender neutral Hunters! Welcome to another week of writing prompts! If you are new here, this is a community-driven weekly event, and the purpose is primarily to generate creativity and have fun while doing so (whether you are a 100% real-meat person or not, we don't judge).


##What will be involved:

Each week, three RWBY-related topics will be posted (subject to ties and special events!). Participants can write a short piece of fiction or dialogue based on that prompt. When writing, the suggestion is to aim for 1k-3k words, however, this is not a requirement. There is no goal - this is not a popularity contest - just write and have fun! If you have any questions, feel free to ask! :)


##Rules (gore, NSFW, spoilers etc.)
The rules are the same as the sub's posting guidelines. Nobody here wants to see your story taken down, so please refer to them before contributing! If someone chooses to ignore these rules, a mod will be asked to remove the post.


##Additional information

Pre-writing is welcome!
/r/rwbyprompts is a sub with writing as a focus - now with weekly events!
A detailed spreadsheet of WPW things is here! Keep in mind that this houses a lot of the old prompts, but it also has links and things like early participation to previous WPW threads. We're trying this whole week-to-week thing in the face of the bajillion prompts we had built up. We might do something with them, or people might cycle them back in, who knows what could happen??

Find us on Discord at The Qrow's Nest! The permanent invite has been deleted due to Discord bot shenanigans, so ping shand or one of the mods below if you want an invite!

Team AJSS can be contacted with questions in addition to myself: These are the mods of RWBYPrompts - JoshuaBFG, Sh1f7er, and SmallJon.

Many thanks to the mods for letting us continue this!

Could an electric car have only regenerative brakes and no conventional friction brakes?

My understanding is that combustion cars have brakes that turn the car's kinetic energy into heat energy, and electric cars have both these conventional brakes and can also do regenerative braking that turns some of the car's kinetic energy into electricity instead of heat. The reason they have both is that regenerative brakes can't apply nearly as much braking force as normal brakes. My question is, would it be possible for regenerative braking to be engineered to be capable of stopping a car just as quickly/effectively as conventional friction brakes can?

[Houndsman: A Base-Building LitRPG] - 38. Friction With Neighbours

[Previous|First|ToC|Discord|Patreon|Next]

This should be chapter 39.

-------

When Ed woke Flint up the following morning, Flint couldn’t help but feel an inkling of guilt. Of the sixty-something new residents in the Woodson fort, forty were human. A little over a third of them were children, and the Heartstone didn’t react to them yet. The elderly were a dozen on the other end of the spectrum, and everyone in between was a teenager or a young adult. Flint had treated the middle group fairly but not the older folk.

The slavers had collected close to three dozen first-tier skill stones. It was a small fortune. Then they had dropped fifteen after death, and half of those were higher-tiered stones. While he stored the latter for the future, he’d freely handed out stones to the younger people. He’d ensured they had at least two if not three nodes filled.

Meanwhile, only the older people who agreed to train younger people got a stone. He didn’t trust the others to live up to their promise and contribute, so he had passed on them. Flint was sure there were people in the settlement furious with him, but he reasoned it was inevitable. He didn’t want to invest in people who couldn’t or wouldn’t contribute.

β€œThe hunting party got back at first light, Mr Flint,” Ed said, handing him his clothes. The young man was already dressed and had a short spear slung across his shoulder.

Flint wanted to fill out the boy’s skill stones, but Ed had only accepted the second-tier skill stone [Spearplay]. It now sat in his [Control Node] while [Aura] and [Power] remained empty. Ed wanted more time to think about how he wanted to progress. Flint had suggested he place [Shield Arts] in one of the other two nodes, but Ed rejected the idea. He wanted one hand free to use [Earth Moulding] on the fly. Ed planned on working in the guard, learn the ropes with the hunting party as well as help Flint help build.

Following a demonstration by Ed, three teenagers had claimed the [Building] skill stones they had gained. The two boys had pl

There is absolutely no use case in human society for "store of value", EXCEPT FOR the SINGULAR use case of "exchanging value at a later time". If there is high friction with exchanging value in the future, then that thing will no longer be revered as a store of value.
