Racism in the United States: By the Numbers

robbersdog49 says...

Here, take as long as you want. All the info and sources are exactly where he says they are, in the YouTube description. I've copied them here for you. If he hadn't provided all of these I might be inclined to agree with you. But he did provide the evidence, so you don't just have to believe the buzz words, you can actually check it out for yourself.

SOURCES

On average, black men's prison sentences are 20% longer than white men's for comparable crimes: http://www.wsj.com/articles/SB1000142...

Black people and white people use illegal drugs at similar rates, but black people are far more likely to be arrested for drug use: http://www.vox.com/2014/7/1/5850830/w...

African Americans are far more likely to be stopped and searched (although the contraband hit rate is higher among white people) in California: http://articles.latimes.com/2008/oct/...

And in New York (where the data isn't quite as good but appears to be comparable to CA): http://www.nyclu.org/content/nypd-qua...

Those wrongfully convicted and later exonerated by DNA are disproportionately African American: http://www.innocenceproject.org/Conte...

Black kids are far more likely to be tried as adults and more likely to receive life sentences: http://www.nytimes.com/roomfordebate/...

Black former convicts get fewer employer callbacks than white former convicts: http://www.irp.wisc.edu/publications/...

Emily and Brendan are more hirable than Lakisha and Jamal: http://www.chicagobooth.edu/capideas/...

On that front, this study is also interesting: http://psycnet.apa.org/journals/apl/9... and similar results have been found in the UK: http://www.theguardian.com/money/2009... and also in Australia: http://ftp.iza.org/dp4947.pdf

Also, this news story has some great analysis: http://www.nytimes.com/2014/12/25/bus...

High schools with mostly African American and Latino students are less likely to offer courses in Algebra II or Chemistry than high schools with mostly white students: https://www.documentcloud.org/documen...

This article explores many of the other ways that increasingly segregated schools have negatively affected African American students: http://www.nytimes.com/2014/12/21/sun...

And this story discusses the fact that African American students are more than twice as likely to be suspended as white students--even in preschool. http://www.npr.org/blogs/codeswitch/2...

"By the numbers", which means "recent surveys", "studies have shown", "a nationwide poll", "let's look at some data", "overwhelming evidence has shown". All the statistical buzz phrases. I would rather see this issue presented in a ponderous TED presentation than this overly glib Michael Moore cartoon short.

To be clear, my problem is with the messenger, not the message.

The Fine Tuning of the Universe

StukaFox says...

"The idea that your cat is the Creator of the Universe has no explanatory power. To have an argument that your cat is the Creator you need to provide positive reasons for it. The Universe is finely tuned: if design is an explanation than I wouldn't need to disprove anything and everything as being a potential Creator, I would simply need to examine the evidence for design to make a determination as to what kind of being this must be, and using Occams razor I could come to some definite conclusions about it."

And I would posit that any same test applied to the Judeo-Christian god would fail the test equally (given that "god did it" isn't a theory, it's a construct). For that matter, so would any other god you want to throw out there. Assuming an intelligent creator pre-dating the universe created the universe calls into question "How did this dude himself go about getting created?". That question can only basically be answered with "It's turtles all the way down".

How do you know that a Universe governed by laws isn't the signature of a Creator?

How do you know my cat didn't create it? Equal empirical evidence (none) of both constructs.

Why would you expect to see a grand cosmos such as this, with such awesome beauty, whirling away with mechanical precision? The mere fact of its existence let alone its operation and stability is something too grandiose to be automatically regulated to some accident.

Really? We happen to live in a time period called the Stelliferous Era in which stars exist. Too far in the past, they couldn't form; too far in the future, they will no longer form. So oddly enough, given that the conditions are at this particular time are favorable to life, life came into being and evolved. So if it's your belief that god created this universe to be human friendly, why'd he wait so long for the conditions to be right for us to exist? Why not just do it on Day 1? Or why didn't he wait longer? Why did the universe have to be human-friendly in the first place? He's god -- he can do anything, so why are humans bound to all these rules of math, physics and chemistry, like every single other bit of life from bacteria to Blue whales?

How do you know that a Universe governed by laws isn't the signature of a Creator?

How do you know it's not my incredibly clever, and possibly deific, cat? Again, same empirical proof (none).

Why would you expect to see a grand cosmos such as this, with such awesome beauty, whirling away with mechanical precision?

We live in a time where the universe is able to support life. Outside of this neatly-ordered era, we'd be plasma or neutrons.

The second question is actually a really good one. I would expect to see the "signature" of the creator: something empirical that would point directly to a creator-being as opposed to a universe governed by. and explainable by, mathematical laws.

Why would you expect to see a grand cosmos such as this, with such awesome beauty, whirling away with mechanical precision? The mere fact of its existence let alone its operation and stability is something too grandiose to be automatically regulated to some accident. The intelligibility of the Universe is also something you seem to be taking from granted. Why should we even be able to comprehend it as far as we do? Could it be that the Creator gave us that ability?

I would also ask you why you think that understanding the mechanism somehow explains away agency?

Bill Nye: The Earth is Really, Really Not 6,000 Years Old

shinyblurry says...

Hi Poolcleaner,

I think you're arguing from a false premise, that a belief in Creation science does not contribute to what you call true science. Some of the greatest scientists who ever lived were creationists. Here is a list of a few of them:

http://creationsafaris.com/wgcs_toc.htm

Their belief that God created an orderly Universe based on laws (which is the reason we call them laws) highly influenced and inspired their exploration of the cosmos. Here are a couple of quotes:

When with bold telescopes I survey the old and newly discovered stars and planets when with excellent microscopes I discern the unimitable subtility of nature’s curious workmanship; and when, in a word, by the help of anatomical knives, and the light of chemical furnaces, I study the book of nature I find myself oftentimes reduced to exclaim with the Psalmist, How manifold are Thy works, O Lord! In wisdom hast Thou made them all!

-Robert Boyle, Chemistry

The more I study nature, the more I stand amazed at the work of the Creator.

-Louis Pasteur, Medicine

Creation science is a collection of data which supports the idea that the Earth is young. Some of the theories within creation science are testable and predictive, but as a whole you cannot put it in a lab and perform a measurement any more than you could do so for macroevolution, because they both concern what happened in the past. You cannot observe macroevolution happening anywhere nor can you subject it to empirical testing. You can make observations and inferences based on a theory, but that is subject to interpretation.

Asimov on Global Warming 25 years ago

deathcow says...

Little known fact but Asimov was cloned on the day of his death, and his clone is now 22 years old. The Asimov foundation payed to recreate (with pretty fair integrity) his entire upbringing, location by location and school by school. Just like his predecessor, the new Isaac is finishing his degree in chemistry over the next three years and is taking an interest to writing.

Bill Nye: The Earth is Really, Really Not 6,000 Years Old

poolcleaner says...

I wouldn't keep beating this horse bloody if yours hadn't died HUNDREDS of years prior.

We're NOT talking about philosophy. This is NOT a perspective based on convictions alone. We are talking about TEST-ABLE SCI-ENCE...

This is the world (universe, perhaps multiverse) which engineers towards space discovery, sustainability of planetary bodies and their varied biology, geology, chemistry, and all of the sciences explainable through the holiest of holy languages -- MATHEMATICS -- based on innovation and implementation through repeatable testing.

Your beliefs do NOT contribute to that, though they do contribute elsewhere -- the realms of philosophy and mythology. I guess we call that religion. But not science.

In this life, we are concerned with temporal discovery and how to engineer with such discoveries. We're not concerned about the afterlife in THIS life. We are concerned with science, especially because it has a track record of proven results which we all benefit from.

It doesn't matter what you believe or once believed, there is a rigorous process for scientific knowledge; including a peer review process. All humans have emotional pain, but that shouldn't hold us back in the dark ages before reason.

shinyblurry said:

I feel the same way Bill Nye does; I don't think they should teach Darwinian evolution to children. It is especially damaging to children to adopt the belief that they are a random accident with no purpose or meaning to their lives rather than a special creation of God, made in His image, and created to fulfill the destiny He planned for them.

Bill seems to think that those who believe in God are simply too weak to accept the idea that we are all glorified apes living on a random mudball, but that isn't true for me or the other Christians I have met. People believe that God exists because an honest conviction, not because they are intimated by the philosophical blackhole that a belief in strict naturalism ultimately leads to. I was a true believer in the secular creation narrative before I came to know that God exists. I was resigned, as some of you are, to die an ultimately meaningless death. I changed my mind because of the evidence revealed to me, not because I was scared about my future.

No, you'd be remiss if you opined blatant misinformation.

While there is a possibility that cannabinoids can inhibit tumour growth, there is nothing even close to a solid evidence base to show that "cannabis cures cancer".

Last Week Tonight with John Oliver: Student Debt

newtboy says...

In California we have a JR/community college system that transfers credits to 4 year colleges. You can take your first 2 years at a DRASTICALLY reduced expense, < $50 a credit the last time I went. You can also go there without a major or plan, just to learn. That's what I did for years and years, building up credits towards a degree without declaring one. It's really sad that that's not the norm, it seems like a great system. Not only does it make entry into 4 year colleges easier and cheaper, it also makes the 2/3 of students that drop out in the first 2 years have FAR less debt (if any) when they decide school is no longer the right option. It also opens higher education up to high school students with aptitude and older people who simply want to learn something new without breaking the bank to do so. This also makes for a better, more diverse student body.
Before someone who doesn't know makes the assumption that the level of education is lower than 4 year schools, you should know that many have been awarded 'best college' and 'best teacher' for the state repeatedly. True enough, there is an upper limit to the classes offered, but advanced molecular organic chemistry, offered and taken at Foothill college, was fairly advanced, as was advanced marine biology, taught by the repeated winner of 'best teacher' in the state. Each class cost about $250. WHAT A DEAL!

How I Met Your Mother - Official Alternate Ending

Sarzy says...

I'm not sure if this is what you're saying (I might not be reading this correctly), but the ending they had from the start is the one where the mother dies, not this happy one. This was a backup ending that they filmed just in case they chickened out.

The problem with the real ending, for me, is twofold:

1) It didn't take into account how great Cristin Milioti was as the mother, and how much chemistry she had with Josh Radnor, which made her death an even bigger bummer. The original plan was going to be for us to only meet her very briefly, which would have made that ending sting a lot less.

2) I didn't take into account that the show was going to run for as long as it did. If the show had run for say, four or five seasons, the whole "Ted is still in love with Robin" thing would have seemed way less creepy and strung along. As it was, because the writers had to continually plant the seeds of Robin and Ted still being in love with each other throughout the show's nine years to make their ending still make sense, it made their relationship seem unhealthy and toxic. The finale comes off as weird and sad instead of romantic.

But yeah, I'll agree with everyone else that the last few seasons of the show were pretty weak. That fart of an ending was just the final insult.

VoodooV said:

The funny thing is that had they did this ending from the start. I would have thought something was missing. It's too perfect/happy. So I sorta understand why they did what they did originally. Still, like Yogi said, the show went on way too long. They never have the good sense to end it when it should and they keep dragging it out for money's sake for way too long until it sucks and we're sick of it.

Also what sucks is that we really don't get to know the mother much. Sure, getting to that point was great. but its still lackluster when they try to cram an entire relationship and a whole personality into one season.

Sen. Whitehouse debunks climate change myths

orintau says...

Newtboy said it well; ice ages come and go due to numerous factors, but one of the most important factors is how much of the atmosphere is composed of carbon dioxide and methane.

Indeed, there have been interglacial periods where the earth was largely void of ice and had the much higher sea levels to match. At one point global temperatures were about as high as is expected to occur in the next century or two.

The difference between then and now is that life and the ecological chemistry of earth had millions of years to adapt before those periods reached their height in most cases. I say in most cases because there have been periods where climate change occurred faster than before and severely disrupted ecological stability or simply caused mass extinctions. Climate change has always happened, but the reason why current climate change is so worrying is because it is happening faster than ever before and because there is a massive amount of data to back it up.

notarobot said:

My understanding, and I am not a scientist, has been that the oceans are most responsible for conveying heat from warmer equatorial regions towards cooler polar regions.

If diluting the ocean's waters makes those currents *better* at transferring heat, then would the heating of the polar regions accelerate as freshwater is added to the oceans and salinity is diluted? If this was the case why would warm periods between ice ages ever stop short of melting polar ice caps completely? And what causes ice ages to come and go?

Sen. Whitehouse debunks climate change myths

orintau says...

Hi Notarobot, your argument is unfortunately based on a very common misunderstanding of the chemistry of water and salt.

I can assure you that it is an established scientific fact that pure water has the highest heat capacity per unit of its mass compared to any water solutions. The less water there is in a water solution, the less heat capacity that solution has. This is because the temperature of pure water is more proportional to the amount of energy contained within it, which is due to the flexibility of its molecular structure. The more salt you add to water, the less structural flexibility (i.e. purity) there is to distribute and contain energy as the temperature increases. To put it another way, the salt molecules weigh down and restrict the water molecules from moving as freely, which is why salt water has a higher boiling point.

So in fact the more fresh water that is introduced to the oceans, the higher heat capacity and heat conduction there will be.

Furthermore, you grossly oversimplify the problem of climate change by assuming the only change that matters is immediately perceptible to "mammals like us". One of the biggest issues is that even slight variations in temperature can drastically change entire marine ecosystems. If enough ecosystems collapse, it will cause a chain reaction that will be very, very difficult to manage, let alone recover from. Also, even slight variations in salinity can drastically change ocean currents, which in turn affects not just marine ecosystems, but weather patterns throughout the world as well.

I can tell you're an intelligent person, so I hope you'll take me seriously when I say that it's very, very important for all intelligent people to be as diligent as possible when referring to the scientific causes and effects of climate change. Advocate whatever position you'd like as to how we should go about things, but please do your best to validate the information you're using to do so.

notarobot said:

One of the results of a warming ocean is melting glaciers and ice caps. That is the addition of fresh water to a salt water system. There is more saltwater than freshwater in the world. One of the properties of salt water is that it conveys heat better than fresh water. The hot-water baseboard heater you use to heat your home would actually be more efficient if it used salt water. We don't use salt water in heaters because salt actually corrodes the metal pipes faster. What does this have to do with climate change? As you dilute the salt water that transfers heat from the warm equatorial waters of the world to the cooler waters in temperate zones, it gets less good at transferring that heat. This change happens very slowly to the perception of short lived mammals like us. In geologic terms, this is how we get to the next ice age.

Neil deGrasse Tyson on genetically modified food

dannym3141 says...

@nock

If we accept that he is a very proficient physicist, then he is certainly able to understanding the scientific method - the attention to detail, the terms, the maths, the statistics.

A proficient physicist can spend weeks analysing a research paper written about their own particular field, needing hundreds of re-readings to understand everything.

I would say, on balance, NdT is very likely to be very capable of understanding of the biology with access to scientific research resources and reference materials. As for the chemistry - a lot of physics (especially the astro) IS chemistry; big bang nucleosynthesis, star nucleosynthesis, nuclear reactions, radioactive decay... Physicists joke that chemistry is just a subset of physics. And biology comes down to chemistry!

I think you're not giving him anywhere near the respect he deserves on this matter. He is not just a physicist - he's a scientist.

(Sorry if i'm a bit like a dog with a bone, i often think that real, well rounded scientific understanding isn't given the respect it deserves - no bias honest! But i would say that NdT could very easily conduct biological research if he found a subject that interested him in that area. Many of the tools are probably the same.)

Tim Harford: What Prison Camps Can Teach You About Economy

Trancecoach says...

Videosift is clearly not the forum on which to teach economics (let alone philosophy or epistemology), but suffice it to say that logic applies to economics, just as it applies to geometry, and the other natural sciences.

Economics follows axiomatic-deduction. Human behavior is too complex to treat empirically (thereby precluding experiments that would be similar to, say, chemistry, which replicates the same results over and over again). With economics, such experiments are impossible because there are too many variables for which there are no controls, so therefore, a deductive approach is used, like with geometry which, if you recall, experiments aren't conducted in geometry, but logical deductions are made based on self-evident axioms.

This is in contrast to what, say, econometricians do. They try to make economics into an empirical science, like physics or chemistry and so they focus on the "science" and ignore the "social" in "social science."

Hermeneuticians/rhetorician on the other hand, ignore the "science" and focus on the "social."
Economics cannot be properly studied as a natural empirical science, but it also cannot be properly studied as rhetoric.

Deductive rationalism is the best fit for economic study.

ChaosEngine said:

"No one is talking about a comprehensive view of everything relating to the world. "

So why are you bringing it up?

We can discuss physics, math, engineering, logic, chemistry without human behaviour. Hell, we could even talk about accountancy.

But economics focuses on the interactions of economic agents and economies. True, some economic agents are perfectly rational and act according to predefined rules (these are essentially software), but almost all other economic agents have a degree of human control to them.

Even if the degree is relatively small (a single person on a board), economies are inherently chaotic systems and a small variance in inputs can radically change the outputs of the system.

The system is essentially stable, but unpredictable.

The ultimate refutation of your theory is quite simple.

If economic systems are inherently rational, we should be able to perfectly model them and predict them. That is clearly not the case.

"No one is talking about a comprehensive view of everything relating to the world. "

So why are you bringing it up?

We can discuss physics, math, engineering, logic, chemistry without human behaviour. Hell, we could even talk about accountancy.

But economics focuses on the interactions of economic agents and economies. True, some economic agents are perfectly rational and act according to predefined rules (these are essentially software), but almost all other economic agents have a degree of human control to them.

No one is talking about a comprehensive view of everything relating to the world. But with economics, like geometry, and the other natural sciences for that matter, yes, they follow logic and rationalism. Rational theories are necessary to make sense of the data.


That you seem to understand nothing about it is a completely different issue.
