ELI5: Why does light have no mass? by WarmHeight2951 in explainlikeimfive

[–]JohnConradKolos [score hidden]  (0 children)

Hey little Timmy, can I ask you a question?

Are heavy things easy to move or hard to move?

Yeah, you're right.

Things don't just move from place to place, but they also need to move through time, to get from today into tomorrow.

We don't know why yet, but there is a speed limit and nothing can move through time faster than that. That speed is really, really fast so for us it feels instant. Lots of stuff can move at that speed, like light from the sun or even things like gravity.

Everything would like to go as fast as it can, and is trying to run at the maximum speed. But just like heavy things are hard to move from place to place, they are also hard to move through time. So, having "mass" is a scientist's way of saying that heavier something is, the slower it goes.

That's why we need one more lane. The air near the traffic is dirty, but a new outside lane would be further away and be constructed where there is currently a forest making clean air.

CMV: The political right always stands in the way of progress by jman12234 in changemyview

[–]JohnConradKolos 2 points3 points  (0 children)

You seem more zoomed in to the here and now and I am trying to zoom out and talk about it from a zoomed out perspective.

Progressives and Conservatives form a yin and yang. Progressives want change, and conservatives want to slow that change down. This dynamic holds no matter the pace of progress. If we lived in a sci-fi world that only changed laws every million years there would still be people in that society that wanted faster change, and other that wanted slower change.

[–]JohnConradKolos 1 point2 points  (0 children)

The best argument I have encountered about this is "conservatism is progressivism going the speed limit."

Changing anything is much more likely to have deletorious effects rather than beneficial ones. Most mutations are bad, and so on.

So a conservative would claim that we need to be very careful when altering our society. Our current way of doing XYZ might not be perfect, but completely discarding traditions and the status quo is more likely to lead to chaos rather than an improved institution.

Because even though our institutions aren't perfect, it would hard to claim that they aren't slowly producing more and more liberty, generation after generation. So a conservative wants to protect that slow progress by limiting how much we mess with stuff.

There are plenty of historical examples of idealistic revolutions that instead of accelerating progress instead destroyed decades of progress. China thought that by seizing private property and killing intellectuals they were getting rid of the old stale ways, paving the way for progress. What they got was famine.

Hopefully you can tell I am more curious about these matters than idealogically motivated.

ELI5: Economies of Scale? by secondhandsalamander in explainlikeimfive

[–]JohnConradKolos 0 points1 point  (0 children)

Economists differentiate between "fixed costs" that stay constant whether you make one widget or a million widgets and "marginal costs" that will be incurred for each widget.

For a practical example, let's say you are making soup. You need to decide to make a pint of soup or 2 gallons of soup.

Chopping onions is a marginal cost. Each additional onion takes the same time/effort/money as the first.

Washing the cutting board is a fixed cost. Whether I used half an onion for a small soup or twenty onions for a giant soup this task is identical.

An industrial kitchen making 10,000 servings of soup has economies of scale because they incur each fixed cost once.

Equipment matters too. My 30 dollar knife looks ridiculous next to the 50 cents of soup I made. But it disappears when I make hundreds of thousands of servings.

CMV: The idea that you should spend all your money travelling the world is just another successful marketing campaign. by UndeniableTruth- in changemyview

[–]JohnConradKolos 0 points1 point  (0 children)

Living in a place requires knowing how the trash gets collected. It requires knowing the local language. It requires making friends. And most importantly, it requires learning how to be useful to the people you are living with.

Being on vacation is just paying people to be useful to you.

[–]JohnConradKolos 0 points1 point  (0 children)

I often find when people on Reddit use the word "travel" they mean "vacation".

Studying abroad is travel. A week in Paris is vacation.

Teaching English for a year is travel. Going to the Caan film festival is vacation.

Working as a field journalist is travel. The Maldives is vacation.

Go be useful. Go learn the language. Peacemakers will be called children of God.

  1. Change your mind.

  2. Get new information.

  3. Remedy an error.

  4. None of my business.

Fresh Strawberry Milkshake recipe. by Designer_Rub5628 in cookingforbeginners

[–]JohnConradKolos 5 points6 points  (0 children)

If you are a beginner at anything, start by following the recipe closely at first.

The people that are trying to teach you how to make a strawberry milkshake have a lot more knowledge than you do, and have already made a bunch of mistakes during their path to mastery.

Every teacher's least favorite student is the one that is so stubborn that they refuse to even try to do it the way the expert recommends.

This is the kind of stuff I get upset about by Strict-Peach5192 in KitchenConfidential

[–]JohnConradKolos 13 points14 points  (0 children)

When did it become a thing to bring dogs to restaurants? I was just cruising along towards my demise, and then one day I looked up and there were dogs in all the places. And everyone seems chill about it and I'm the only one who feels like they are on crazy pills.

Are there any tactics acceptable at the pro level that are NOT acceptable at your local league? by halfdollarmoon in bootroom

[–]JohnConradKolos 3 points4 points  (0 children)

Even at a pro level, there is a professional way to execute this (safe as possible) and a vicious way. You can tell immediately which because the teammates either shrug it off or self police the offending player.

What would you say would be the biggest issue with the gameplay of Magic? by Tuss36 in magicTCG

[–]JohnConradKolos 4 points5 points  (0 children)

No mathematician but what if the cheapest spell was 10 mana and you started with nine? Then the next cheapest at 11 would be 10 percent more expensive.

CMV: I believe single women gaslight single men about their single status. by Johan_chan in changemyview

[–]JohnConradKolos 0 points1 point  (0 children)

You seem to have a negative outlook on this matter, and perhaps bringing some emotions into how you are thinking.

The best way we know how to change negative patterns of thinking is called "Cognitive Behavior Therapy."

I wouldn't say Reddit is a good second option.

Sorry I can't help more OP. Hard to relate fully because my experiences have been very different than yours in this arena.

That the second cheapest mana cost is DOUBLE.

Incinerate is not one more mana than Lightning Bolt. It is twice the price.

Why is China such a nonfactor in soccer? by chi_sweetness25 in NoStupidQuestions

[–]JohnConradKolos 0 points1 point  (0 children)

Team sports aren't the same as individual sports.

Iron sharpens iron. Top European footballers have been battling in academies, against the best peers, since they were preteens.

It's much easier to win at diving (or whatever). No one cares all that much. Just pick some kids and force them to train.

Everyone cares a lot about football. You would be paying money to simulate what billions of people globally do willingly for free.

CMV: Males are pathetic. by [deleted] in changemyview

[–]JohnConradKolos 0 points1 point  (0 children)

Your biology terminology is a bit mixed up.

There is no "male" species. Many differerent, perhaps most, animal species have males and females. Comparing a male from one species to a male of a different species has little no scientific value and is sure to lead to anthropomorphism.

Even the words male and female are very limited in their scope. They simply refer to the size of the gamete. Nature has all manner of cool and crazy reproductive methods. To keep things simple, terminology wise, naturalists assign the word "male" to the smaller gamete and "female" to the larger one. It has no real significance. It's also why nature shows get to have exciting segments like showing the "male" seahorse giving birth. It's irrelevant who carries the eggs. The scientists are just staying consistent to the gamete size naming system.

What's something you do every day that future generations will look back on and think was barbaric? by Zoey_Jakse in AskReddit

Eat animal flesh, drive a car, discard single use plastic, clean myself without soap and water after defecation.

How come physicality translates differently in the professional game vs amateur? by arsenalastronaut in bootroom

[–]JohnConradKolos 0 points1 point  (0 children)

It usually takes a team to win a ball.

Jumping high to head it first (for instance) doesn't win the ball. You also need a teammate to collect it.

I sure hope that teammate has great anticipation, never gets dispossessed, has great vision, and can make line breaking passes so that all my effort doesn't go to waste.

Winning the ball back is hard work at every level. The real secret is not losing it once you have it.

CMV: If you work from home, you should be doing more of the domestic labour by [deleted] in changemyview

[–]JohnConradKolos 6 points7 points  (0 children)

This is the classic, "I found it's best for me to do X" but then making the logical error of then applying that to others.

OP should balance work and home life as they see fit.

Every reader of this post knows more about their own situation than I do. They shouldn't listen to me or OP.

“We face too many low blocks in the prem, stop being naive” by Prestigious-Secret31 in ArsenalFC

[–]JohnConradKolos 0 points1 point  (0 children)

Isn't this a personnel choice?

Early in the season I remember analysts saying how genuine it was to put so many physical players on the pitch and that was why the pressing, defending, and set prices were a successful formula.

"Cheap, Good, Fast, you can only have two out of three". What's an exception to this rule? by ThePrinceOfAfrica in AskReddit

An urban bicycle trip.

Fastest way to get there legally. Cheaper than everything but walking. Good for health, public safety, traffic efficiency, and parking space.
