Bridge opening, ribbon cutting ceremony

newtboy says...

It looks like they just took 2 flatbed trailers and chained them together in the middle.

On second look, it also looks like the foundations both collapsed too. One split, one leaned over dangerously.

Better this happened now than in the wet season when it definitely would have failed and dumped people into the river.

They should name it Corsair bridge….unsafe at any speed!

Color video of Albert Einstein actually explaining E=mc2

newtboy says...

Good, then I’m not just being dumb….But you don’t recall at what point it goes from KE= 1/2m V^2 to E= M C^2 …or the equation/function used to determine energy below the speed of light but above the 1/2 threshold?

Somewhere below C (speed of light) it gains up to 1/2 the total system energy, beyond simple kinetic energy…I’ve heard this alluded to as mass becoming energy, but never with any explanation how or even if that’s reality or just a mathematical “trick” to make the equations work…nor an equation describing the process. I only took year one physics….over 25 years ago.

Actually, I think I can verify this. I remember in physics going through a derivation of why E=mc^2 and being very disappointed that it was just a specialised case of your second equation.

"A Fourth Car Absolutely Buggered!" - Deadly Mexican Street

luxintenebris says...

Lived near an intersection where one got used to hearing auto crashes. Whenever it sounded like someone dropping a refrigerator off the back of a truck - it was time to call 911.

Know of a house in CA that was hit 7 or 8 times because of the road design. Took years for homeowners to get the officials to improve it.

it'd be the home to the right of the 'turnaround' area behind the rock (which might have been the homeowners' first solution to the problem - a few deaths just might get officials to take it seriously). Also if you zoom in on the north side of the house, there is a patio doorway. That's the area where it got hit last. Maybe it was easier than fixing the wall?

the high traffic street use to just slope off into a residential street. some folks didn't know the road ended despite some signage. most just travel not knowing it ended couldn't stop in time or missed the turn at high speed.

Fascinating creation of a LEGO inspired, wood coffee table

newtboy says...

I found it odd that, while the table has 8 holes, he gave it 3 legs. It doesn’t look right to me like that.
Even a 2x speed, a bit long, but quite detailed to make up for that.

Kilian Bron Best Of 2021 POV Mountainbike Lines

BSR says...

I wonder if they make test runs before doing the high speed runs. This is worse than Free Soloing a mountain. Not only would you fall to your death but you would also wreck a perfectly good and expensive bike! Not to mention the camera.

Edit: Don't know how they can ride like this with such big balls on such a small bike

Overtaking With A Steam Engine

luxintenebris says...

The 1924 model Doble Series E steam car could run for 1,500 miles (2,400 km) before its 24-gallon water tank needed to be refilled; even in freezing weather, it could be started from cold and move off within 30 seconds, and once fully warmed could be relied upon to reach speeds in excess of 90 miles per hour (140 km/h).
-taken from https://en.wikipedia.org/wiki/Doble_steam_car

steam was a thing. alone w/electric cars. what really was impressive was the steam driven airplane.

Trump Wanted Armed Groups At His Jan 6 Rally

newtboy says...

Incorrect, as pointed out above. Some second hand accounts of tantrums, and many first hand accounts of criminal activity like knowingly inviting heavily armed thugs into his crowd to prepare for his planned attack of the capitol building and saying Pence deserved to be lynched so Chump wouldn’t make a statement telling his people to stop as his thugs actively hunted the Vice President in the halls of Congress. She witnessed those first hand. I know, you’re just repeating what some liar told you, and you have no first hand knowledge of her or anyone’s actual testimony because you aren’t allowed to watch the hearings….so your arguing over your own second and third hand accounts filtered through biased liars.

Note, the secret service was so in Trump’s camp that Pence refused to get in a car with them because he believed they would murder him or deliver him to the murderous crowd….the one allegedly denying it, Ornato, still works for Trump today (and hasn’t actually denied it, there are just reports claiming he WOULD….and Ornato has been accused of lying for Trump repeatedly including personally telling the blatant lie that Lafayette square wasn’t violently cleared for a Trump photo op at a nearby church….


Get his denial under oath then try again.
Edit: today the story from Trump’s team became “Trump was too fat and out of shape to lunge for the steering wheel.”, which if true made him too fat and out of shape to reach out <3ft, which makes him far too fat, feeble, and near death to be president.

Keep your head up your ass if you wish. You’ll find yourself alone in there.
Why not call them to testify? Because that bit, while salacious, is hardly the main point or even a crime that might be prosecuted, so why waste time on red herrings. I know you wish they would focus on his infantile tantrums, they distract from his treasonous terrorism.

This woman worked 10 ft from Chump. She was a personal assistant for his chief of staff, you would expect her to be about as loyal as they come to be in that high position with direct access to the president ….and his behavior was so intolerable and anti Democratic she tanked her career and personal life to expose it. Do you have any reason why she would lie? There are many reasons why she wouldn’t have testified, including the death threats against her if she did. She’s clearly from team Trump, not an anti or never trumper.

Fools like me, and around 70% of everyone else….everyone not in the cult with full blinders on, and even some who are. Your little world is crumbling, your great leader exposed for the petulant child and treasonous terrorist leader he is, publicly. Fox is running away, republicans are running away, independents are flying away at supersonic speeds.

You would know about drinking bath water. How does Trump’s ass crack taste?

Edit: You know this is the Trump methodology….
1) deny you did “it”
2) equivocate, claim “they do “it””
3) still deny, but insist it would be fine if you had done “it”
4) admit you did “it” just a little
5) revel in the fact that you can now admit you did the evil inexcusable thing and more without your base caring

A show trial of 2nd hand accounts.
Even the agents involved denied this ever occurred. Why weren't they called to "testify"

Fools like you are lapping it up like AOC's bath water.

Normal Bike Math - .5 Wheel x 2 = 1 Wheel

cloudballoon says...

That's some ingenous skill/science of a solution... in search of a problem.

This is a wholly self-induced problem. Just slow the F down going up/down a curb... Ironically, try to ride this thing at speed and see how it'll shatter into pieces even quicker than a busted wheel.

Gets an "A" for effort though, hard to find a kid/YA with such dedication and curosity to science nowadays.

Russian soldier caught with his pants down

cloudballoon says...

Is that an intentional miss, or? The payload seems very light or not weighted for a more controlled vertical drop. Besides, looking at the rather static foliage, wind speed seems minimal. Seems like the drop is just meant to - or barely just powerful enough - to scare and not kill.

Big dreams, but remember hyperloop, the amazing high speed public transportation Musk foresaw?
It was going to be autonomous pods driving hundreds of mph through multi tube vacuum tunnels, now it’s Tesla cars manually driven maybe 40mph through small one lane tunnels, with traffic jams already on the tiny test track ride in Vegas during the pandemic with riders limited to well under 1000 per hour (<1/4projected capacity) costing $52.5 million for 1.7 miles of inescapable death tube…. so underground death trap roads at only 8800 times the cost of above ground roads.
Remember the Tesla semi truck? Sounded great. Turned out it had less than 1/6 the cargo capacity of similarly size trucks because of battery weight and a 300 mile maximum range new (quickly dropping as batteries age) for the regular version, and unless you charge at Tesla with guaranteed discount electricity it’s not even cost effective against regular trucks per mile, much less per ton of freight….and still not any on the road, now estimated to start next year…maybe.

Notice the teslabot doesn’t list expected battery life, which is the big limitation on self powered robots. All the ability in the world is useless if they need to recharge every 10 minutes.

Elon’s ideas sound amazing until you look at them practically, and find that his projections are insanely unrealistic.

Edit: in his genius, Musk lobbied hard against the infrastructure bill that includes money to build the American chip manufacturing capacity…and now his plants are losing billions per year because they can’t get chips.

I respectively disagree.

This is the buy of the year. 40% off from its high. Not from anything Tesla has done ( or not done) but from the economic state America is going through.

I don't think this will turn around till our leadership changes in 2024


Since last qtr 2021 Tesla opened 2 Giga Factories Texas and in Germany. They are ramping up and will get full speed in 2 years. This year expect 200 thousand from these as they ramp.

Giga Shanghai was shut down and lost 50, 000 vehicles of production. They reopened fully 2 weeks ago . China economy is taking a big hit. But what isn't sold will be ship and sold elsewhere.


2022 yearly estimate production is still about 1.5 M vehicles for the year.

Wait time from order to delivery is average 7 months. Tesla increase their prices 8 times last year to keep this 7 months from getting worse.

Demand out strips supply.


Gas at 5$/gal isn't helping the ICE vehicles at all and will push EV demand even higher.


Like I said

This is the buy of the year. 40% off from its high.
Also looks like a stock split of 3 to 1 is coming. This does nothing but make it cheaper for those who would like to enter this. One can do so at a lower, affordable price point.



Buy and hold



Buy 10 shares and hold for 5 o 10 years.





FYI.
My dad passed away last month on the 28th. I've been out of work tending to him and now settling the estate.

newtboy said:

Ouch. From $1222 to $702 and projected below $600. Gotta sting for anyone who took @bobknight33 ‘s advice, especially anyone “all in”.

The idea that it might bounce back like it once rose is naïve too…with serious production and labor issues and no longer being the only game in town, not even the best anymore by multiple different measurements, Tesla is looking like it’s bubble might be bursting.

Ouch.

The Dutch Know How To Party

moonsammy says...

That's absolutely happening here - it's a really good practical example of the speed of sound. It doesn't really take much distance for the effect to be noticeable - I was in marching band in high school and when we were spread out across a football field it was *really* important we pay attention to the conductor, or everything would end up sounding super muddled to the audience.

Is it me or can you see the crowd father away from the stage lagging behind a bit?

If you have a venue sufficiently enormous the sound does take a little longer to travel back. I'd be super excited if that was the case!

President Biden responses beautifully

luxintenebris jokingly says...

sweet jeezus ivan, the question WAS about musk's (and diamond's) 'super bad feeling' about the economy.

the president answered w/direct examples of other companies' investments in the FUTURE of the economy.

it isn't mental acuity or citizenship causing the problem on this end.

and brain aneurysms? sources? it makes little sense to ask others to search for proof if you've already found it. speed things up a bit. right? [would think a person would be in a hurry to prove someone else wrong.]

BTW: ever notice how folks on the lower spectrum of intelligence are more drawn to supremacy movements?

the same phenomenon happens w/people who like to use words like 'moron'.

Anom212325 said:

The question was about musk's comment in regards to the US economy... Not about one of musk's companies.

is that a reference to the previous senile president you morons chose ?

Google how many brain aneurysms Biden had and while you are at it look at videos of him before and after. You Americans have been choosing one dumb fuck after another screwing over the world thanks to your stupid tribal bs hate for each other.

Hayes: NRA "Good Guy With A Gun" Theory Failed In Real Time

newtboy says...

The proof that these assholes don’t believe their “good guy with a gun” lie is they don’t allow guns at the NRA events.

I wish some nut(s) would attack the NRA event, shooting a few dozen gun proponent politicians that normally hide behind their armed security and bullet proof podiums. I’m sure their tune would change significantly if some of their ilk were silenced permanently. No one deserves it more than Abbot.

Edit: BTW…more unarmed school children have been murdered in school this year than police officers in the line of duty. For all their bravado, their whining about how dangerous it is to be a cop, the necessity for more militarized equipment for their safety, it’s actually more dangerous to be a 10 year old student. I guess those kids should all get vests, rifles, pepper spray, armored vehicles and buildings, etc. ..that’s the solution.

Also, guns are the leading cause of death for children under 19 …have been since 2020.

Fucking worthless cowards and thugs, every single one. They deserve one more bullet each…delivered at high speed.

Rich Strike winning the Kentucky Derby is nuts

I don't know shit about horse racing, but that final run through traffic and then with such acceleration/speed down the stretch looked crazy.
