Tiny Bombs in your Blood - The Complement System

Spacedog79 says...

Each to their own, I thought it was great. It's a small glimpse into the mind bogglingly complexity of biological systems that most people have no idea even exist.

Kurzgesagt has a history of taking something overly complicated and simplifying it to the point where it looses it's meaning and slips into fantasy-land. With this video, it bridges too many concepts and strings them together, until it becomes unsure what the actual path is.

It does handle a more complex occurrence, so It tries, but it loses it's momentum as it gets going because it consists of too many gaps in facts to complete a proper narrative.

Jim Says Christian Leaders Will Be Murdered If Trump Loses

cloudballoon says...

American church leaders dying left & right? yeah... I'd chalk them up as God smiting them for being false prophets.

I'm a Christian (Canadian), but I see American Christianity as a beast of its own. Nuts cases everywhere that rather get in bed with the NRA and the military complex than practice anything Christ says. Total madness.

New Math vs Old Math

RFlagg says...

I get wanting kids to understand what is going behind the scenes of the math problems. It's a good goal, but I do think they spend too much time on this portion. Show how to do it the shortcut way that most people know, show how it works, using the above, then back to the shortcut. Unless the person is entering a math field, they likely don't need the number theory.

It's not dumbing down, it's making it too complex for what most people need. Especially for those taught the old methods... of course "new math" is more like really old math, before we found shortcuts that we use now. The people who'll need number theory, will need to know how numbers actually work behind the scenes of what you are doing, will likely have a more intuitive understanding of the processes.

What needs to be done more is order of operations, so 6 / 2(1 + 2), isn't calculated as 1, and properly as 9... if I see somebody argue 6 / 6 is 1 ever again... There's another famous one that really messes up many calculators, because they do as entered, and don't wait for the equal sign to be entered. With a proper understanding of order of operations, they can use a calculator and get a correct answer. And that is more or less what "new math" is trying to teach in a very odd way...

Minute Physics covered Order of Operations well.

New Math vs Old Math

Payback says...

I would piss off my teachers, and later profs, by never showing "my work" on complex algebra. Kept doing it in my head.

"Find for X"

X=3.56

WRONG!!!

It isnt 3.56?

Yes, but you didn't show your work.

Meh.

Beats me, I learned the old way and it worked for me through algebra 1/2, and geometry.

Neil deGrasse Tyson - Science in America

newtboy says...

That is certainly what your ilk is hoping, and it is why they politicize any science they dislike in order to attempt to discredit it.
Sadly, so many don't have a grasp of the science and are so entrenched in their political team they simply take their lying spokesperson's word for the truth and never look for themselves...they couldn't understand if they did, they aren't scientists. (Neither are your spokespeople)

Climate change is a great example. You won't find a scientist who's a climate change denier that doesn't or hasn't gotten funding from energy corporations or their cohorts, often washed through donation companies to hide the source because they know it discredits them. What you apparently fail to grasp is the right is the group politicizing and confusing these issues, usually for monetary gain....sometimes over ancient divisive doctrine....never to reveal the "truth" or facts about a complex situation, that's simply not important to the right anymore, not a whit....I wonder if they're even capable of comprehending something complex anymore, certainly doesn't seem like it.

Grooveless metal engineering

bremnet says...

No, it's not EDM. It's machined. We produce a variety of cylinder / piston pairs, some with keyed anti rotation or beveled flanges to prevent pull through. The achievement of a visually seamless interface between two parts is certainly not trivial, but with care and the proper sequence of machining steps (guess which face you mill last? right - the one the user sees as seamless) you can do this on good quality CNC's with the right cutters. EDM'ing the complex curved shapes that truly mate across the surface on the early parts shown in the video is very (prohibitively) difficult, as you have to rely on ram EDM which is plain nasty.

worthwords said:

It's a type of electro discharge machining. It has been around for a while but it's so damn satisfying!

Public Shaming

BSR says...

I think forgiveness could fix this complex problem. Forgiving is not the same as condoning.

When you forgive someone, the person you are ultimately forgiving is, yourself. That becomes clear when, one day you are forced to judge yourself by your own bible, written by you over the years with prejudice.

If you don't practice forgiveness, you'll have to live with yourself and your truths.

Or..., not.

WE ARE NASA!

Ashenkase says...

Come on NASA,

The shuttle and now the Orion spacecraft have been and are designed by congressmen and women for make work projects in their states.

The shuttle, although a marvel of engineering, was a death trap due to putting the most venerable structures down the stack.

ISS is a fantastic endeavour, but its low earth orbit and NASA has been struggling with a new direction for decades. The moon... no wait... asteroids... no wait... Mars... hold on... the moon.

Just PICK ONE, at least DOUBLE the funding to NASA and make whatever new project a national initiative. The American space industry can do unbelievable things when the proper foresight is put is place backed by money. (hay, maybe take some out of the military complex?!).

We will see if the Moon remains a target for NASA, maybe that will change when your current "leader" is removed... I am mean voted out of his "office".

White House revokes CNN reporters press pass

newtboy says...

Or perhaps that they stopped her to accuse her of a crime, confront, and challenge her. None of your definitions include this "in error or being rude" inference you want to draw from it, that's your bias twisting definitions to suit your faux outrage.

I accosted my wife at the door with surprise plans to go out to dinner. I would use that sentence. I'm 48....not sure what generation you're from.

What nonsense are you spouting now...no one said she shouldn't have been accosted, you just take umbrage with the term for some reason, so decry the report as biased fake news or something.
Using the proper word to describe events is nothing like Fox making shit up. I don't have a clue what you mean.

Too late, I'm bald. That excuses me from having to watch any more Faux news. ;-)

Derp. That would be a Trump, not an Accosta.

Have fun with your persecution complex. I find you ridiculous and incapable of honest evaluation. Bye now.

If someone accosts another person, especially a stranger, they stop them or go up to them and speak to them in a way that seems rude or threatening.
[formal, disapproval]
A man had accosted me in the street. [VERB noun]
Synonyms: confront, challenge, address, stop More Synonyms of accost

Word Frequency
accost in British
(əˈkɒst )
verb
1. (transitive)
to approach, stop, and speak to (a person), as to ask a question, accuse of a crime, solicit sexually, etc

It is suggesting the police were in error or were being rude at best.
This is how most people of my generation would understand the term.
So all I have to do is shed my clothes now and let things swing in the wind and I can do whatever I please, even coming within feet of the potus?
I don't think It would be a pretty picture/outcome for several reasons.
Biased reporting.
Just because Fox does it doesn't make it right.
You admit you can't even stand watching Fox for more than a couple of minutes.
You therefore have no ground to stand on.
You must endure it until your hair starts falling out as I have with CNN.
That's about 5 minutes.

Another definition might work as well.
The reporter constantly berated,grandstanded and hogged the microphone refusing to show an ounce of decorum.
He pulled an Acosta.

White House revokes CNN reporters press pass

mentality says...

"There is plenty of scum to go around on both sides."

Ahh the classic false equivalency that Trump supporters often resort to.

First of all, every child should be taught at a young age that just because other children may act like little shits, that doesn't mean they can. The amount of functional adult Trump supporters who use "the Democrats are bad too!" as an excuse for Trump's behavior is just astounding. It's really just a pathetic diversionary tactic used to avoid discussing the issues at hand.

Second, your claim that Democrats are just as cruel is simply not true. Blaming Democrats for the very thing Trump is guilty of is a common smear tactic employed by extremist right wing propaganda.

Take Trump's zero tolerance policy which separated minors from their families for example. Right wing propaganda outlets like OAN love showing pictures of children housed alone in Obama era detention facilities and cry foul at the liberal media at the lack of coverage. The reality is that Obama faced a huge surge of thousand of unaccompanied minors from south america in 2014 who were detained. So yes, thousands of children were detained, but they were NOT separated from the families in the first place.

And while some families were separated during Obama's tenure, Obama's policies tried to limit this as much as possible. It is a far cry from what Trump's zero tolerance policy accomplished. The "liberal" media did not report this under Obama OR Bush simply because it was not an issue. If you believed that there was unfair media coverage for Trump on this issue, then you were lied to and manipulated. Its part of what we discussed earlier how Trump uses lies to discredit the media and further erode our democracy.

The point is that right wing propaganda and Trump himself routinely uses lies and deception to paint himself as the target of a "liberal media bias" that they themselves manufactured. And his gullible supporters like yourself love believing in his victim complex. If you don't believe me, then just refer to non partisan international sources like the BBC and you'll soon discover that Trump is just as shitty from an impartial view as the "biased liberal media" portrays him.

Both sides are not the same, no matter what lies Trump and Fox News et al. tries to tell you. And there are plenty of respectable media sources which are not CNN which also exposes Trump for the lying scum that he is.

Briguy1960 said:

It has nothing to do with what I personally like.
This is the issue here.
You despise Trump and so does the liberal dominated media so they gloss over shit the Left do and come down harder on Trump etc.
There is no excuse for the garbage reporting going on.
None.
I suppose you think Kavanaugh was treated fairly too.
The Fusion thing is all just a pack of lies concocted by Alex Jones etc too right?
Blatant showboating about how cruel Trump is when it has been proven time and time again the Democrats held the same views and would never let caravans in...
Funny how things are viewed when you are a religious fanatic as the left is becoming in their
rage against all things Trump and GOP.
Keep looking at things through rose colored glasses my friend.
There is plenty of scum to go around on both sides.

Vox: Why we say “OK”.

MilkmanDan says...

Great sift, I find that kind of stuff massively interesting.

Reminds me of Cockney rhyming slang, which seems like a completely counterproductive layer of complexity impeding the basic intent of communication. But I imagine that given the right circumstances, some Cockney rhyming slang phrase could take off and go global...

McCain defending Obama 2008

ChaosEngine says...

It’s funny that, aside from bob himself, no one has proposed (or even mentioned prior to this thread) banning him.

Personally, I think he’d love to be banned. It would fit his martyr complex perfectly.

I agree with you here. I don’t think he’s a troll; I think he genuinely believes the awful stuff he says.

C-note said:

Banning you would be absurd. You are one of the most genuine individuals here.
