This is outright proof that climate change is a PR hoax. There is no "science" when you can switch predictions at will.

The people are being lied to.

The whole point of science is to adapt its predictions to fit the new (and old) observations, you fucking retard.

Warming increases risk of summer drought and winter floods at this latitude. This was predicted decades ago by climatologists. The second article explains this, but of course you didn't include that part because you want to make this seem like a contradiction.

Who here has transtioned from a brainlet to a math god? How did you do it? I love math but am slow at it. Any tricks on improving mental math or math skills in general?

The helium can't run out if we have large enough supplies of nuclear waste.
Start building those reactors, boyo.

Let's say a 1km diameter asteroid hit the center of the pacific ocean, hit dead straight and not on an angle, how deep/far away would a submarine have to be to survive the shock wave? Will the shear force, no matter how far the submarine would be, break the submarine to pieces? Or is this all impossible to hypothesize?

Depending how fast the asteroid would travel. As soon as I'm home I'll do the calculation

In such an event you have higher chances to survive in a 100m underground shelter than 2km deep undersea.

well it's not really, it's a large mixture of indirect sources

the teachers that tell you not to use it are retarded, but you should never cite wikipedia; you have to make sure the statements you're citing have sources and then you can use those
>>
>>8688685
good question. people claiming this shit probably never use wikipedia themselves. I mean, it's a continuously changed/updated source of information, so it certainly does not serve as good reference for scientific work, but it's a damn good starting point for your research
>>
It's not for general information but speaking as an editor, you'd be surprised at how fucked up the site is from behind. Disputes in talk, fucked up categories and not to mention that 'facts' are a lot more nuanced than you think and incorporating them into an article with many different interpreters is not exactly easy.

Especially when say, a historian, general or scientist used a word in a qualified sense or people misinterpret a word/quote and you have to write a whole section as to the history of that misinterpretation or why the word/etymology of that word matters etc.

quick graph breakdown: [pic<<] or full graphs dump@https://warosu.org/sci/thread/S8575247

facts (really... youd have to see the graphs):

* 1975 vaccine spike from 1 or 2 to 7 vaccines
* also coverage spike to 99% of people get it now, not 25%
* they proceed to double the vaccine every 5 years
* this is powerful math... we can see disease rates in graphs caused by vaccines (theory)
* all diseases go up, graphs here: https://warosu.org/sci/thread/S8575247
* birth defects miscarriage, abortions go up
* autism retardation go up
* sperm count and fertility drop
* manboobs 10,000% increase

>all reproductive related, the vaccine is a ufo, flys to the womb, a body part that grows humans all day, to restore its self into a humanoid, the vaccine was someones food that escaped their stomache in 1900, and is partially digested and needs the womb to restore? and was harvasted in 1900 for a vaccine because it was a nicer pirate/alien/mutant hybrid killer. and given to all of us.

theres a whole nother bit if thats true about **hormones are really people fucking/coupling?** and the vaccine is hot alien sex all day -> alien hormones -> manboobs and other problems....

**so i think u can test this for yourself** with some critical thinking?

* find the vaccine in ur arm say dont show me ur ufo (reverse psychology seems good)
* find a hormone and ask it if it has a boyfriend, or if it lays eggs, or whatever


just my 2cents. working on an article and need to compare to another countries data, but this is what i have so far.

Is there anything more beautiful than the realization that there are infinite multitudes of midpoints for the infinite amounts of diameters for the infinite amounts of hyperbolas for any given cones, and these infinite multitudes of midpoints taken together comprise the infinite conjugate diameters that result from the infinite possibilities of infinite hyperbola's diameters taken out of a given pair of hyperbolas?

A few years ago stem cells were the holy grail of medicine, supposed to cure uncountable diseases and revolutionize the field.

What happened?

Was it just hype from the media?
Or were scientists themselves too optimistic?
Did any unforeseen problem show up later on?

Today it seems stem cells didn't amount to much.

The media fucked off about how evil/miraculous they are so you don't hear about them as much. There is massive amounts of research looking into various types of stem cells, as well as applications

But yes it turns out that like everything involving research, it's more complex than first thought
>>
>>8687890
So in the end it was scientists being too optimistic about something new + media hyping it to sell articles?

Do you think stem cells will eventually provide a breakthrough? Or are the applications less amazing as expected?
>>
>>8687895

Now that Trump was elected start saying goodbye to any meaningful research such as this.

Anti scientific views are cancerous.

Dolphins were 4 legged mammals that adapted to water and it looks like it already reached its best outer design as it looks very similar to sharks.
Humans didn't move using 2 legs before and there is no other animal that has done that for billions of years, have we reached the most efficient design yet, are we just getting started, or in the middle?

I think the fact that dolphins evolved to breath out of their backs instead of their mouth is weirder than them being mammals. How did this happen?
>>
>>8687716
It's not out their backs, it's on the top of their heads. Imagine our noses moving slowly upwards and eventually it became the blowhole we know and love
