People That Like Winter, And Cold, Are Freaks

He needs to get laid

Barring that, maybe he should have a drink or two.

Praise be to Allah if he manages both simultaneously

Scientific research shows that one can lead to the other.

[Al B. Sure!]

This would go a lot faster if I didn't have to click back into excel after every day.

Okay so far I have keyed the highs and lows from the first 10 days of January from 2010-2004. So my preliminary look is 70 days in early January.

There have been 16 days with lows below 32F and only 1 day with a high below 32F.

22.8% of lows have been below freezing with only 1.4% of highs having gotten below that threshold. Considering that the lows are most definitely all night-time temperatures, I'd say a cold day defined by below-freezing temps in early January in Dallas is rare indeed.

Do I need to continue for the rest of the month?

[DaShi]

Yes and go back about 50 years as well. We need to be sure.

[Lorizael]

Do I need to continue for the rest of the month?

Yes. And you should do November, December, February, and March, too. The data must be accurate.

Edit:

[rah]

Please do.

[Imran Siddiqui]

Fine. I'll get you more data points. Going to take ****ing forever to key them all in.

This is the greatest thing ever!

that's slightly over 1/5.. if you keep that trend over all of january, you can expect the equivalent of one week below freezing, which I would say is indeed cold.

Also, one out of four is hardly 'rare'. It's like saying oxygen in the atmosphere is rare...

[Al B. Sure!]

**** that ****. you're all laughing at me.

what the ****. certain people want to claim that winters are frigid in Dallas and Atlanta and everyone just piles on me when I claim rightfully that they are not cold. I didn't think that would require any data since it should be obvious but I gave some limited data. I refuse to believe everyone on here honestly thinks that Dallas has cold winters and that more data would be needed to convince them otherwise. If you do, then you're hopeless and I really question your intelligence. The bizarre thing is you should all be laughing at Sloww and Imran for suggesting that it's cold down South, not me for showing that a cold day (represented by a high temp below 32F) in Dallas in the first 10 days of January has only happened once in the past 7 years. How that isn't sufficient to say that generally speaking Dallas winters are not freezing cold is beyond me. How much data is required to confirm what should be obvious?

It's ****ing Dallas, Texas. TEXAS!

Most of us develop a sort of intuitive logic about how the natural world works. Unfortunately, a lot of that informal reasoning turns out to be wrong, which complicates scientific education. But as students make their way through the science education pipeline, they should gradually start moving beyond the informal reasoning of their earlier years. Or at least that's what we'd like to think; instead, a new survey of college students, some in advanced biology classes, indicates that most end up with a confused mix of formal and informal reasoning.

The clearest example of the chasm between a typical intuition and scientific reasoning comes from the world of physics. Imagine a marble rolling around a curved track that comes to a sudden end. Physics tells us that, as soon as the marble is off the track, it'll continue moving in a straight line until it runs into something else. But many people use informal reasoning and conclude that the marble will continue to follow a circular path even after it escapes the track. In other contexts, it involves an interventionist view of the world. As the people behind the survey put it, "When using informal reasoning, students look for 'actors' that drive 'events' and are aided by 'enablers.'"

Scientific education, then, needs to convince people to move past their intuitions (at least if they want a more accurate picture of how the world operates).

The new survey tested for informal reasoning in the biological sciences, using over 500 students at a variety of colleges, enrolled in classes ranging from introductory biology to advanced ecology. The results show that, even as the students are immersed in things like trophic pyramids and the Calvin cycle, they don't always come to grips with basic things like conservation of matter and energy.

For example, most students could describe how the process of photosynthesis involves removing carbon dioxide from the atmosphere and combining it with water to form carbohydrates, which then get used to build the cellulose that forms most of the plant's bulk. But, when asked to actually trace what's going on on the organismal scale, many students have problems recognizing that a substantial proportion of a tree's solid bulk originated from a gas, instead suggesting that most of it was brought up from the soil.

The problems work in the opposite direction, too. When respiration breaks down solid matter, most of it is released in gaseous form, as carbon dioxide and water vapor. But the students often had a problem with recognizing that a solid compound could be chemically converted into a gas.

In the same way, they seem to believe that every leaf contains a miniature Mr. Fusion, since they think that some of a plant's mass comes from the transformation of one atom into another. Nearly 70 percent "chose 'sunlight' as a possible source of atoms in chlorophyll molecules," according to the results. They had problems with other aspects of energy, too, not recognizing that moving up a trophic level in an ecosystem generally entailed the loss of energy to the environment—"only 44 percent of students thought the top of a food web would have 'less available energy than the trophic levels below it.'"

Other problems noted by the authors include the use of energy as a fudge factor to make things balance out, and a tendency to substitute a wall of scientific terminology for actual understanding.

In all, the majority of the students used a mix of scientific and informal reasoning on the surveys, with about 20 percent using informal reasoning alone. More depressing still, the authors designed a short course to help introduce formal scientific logic, but it didn't help much. The course shifted more people towards relying on scientific reasoning, but the percentage of students who relied on it exclusively rarely exceeded 30 percent, and was sometimes in the neighborhood of 20, depending on the topic (on average, it went from 12 to 27 percent).

What's the root of this problem? The authors ascribe a lot of it to language. It's quite common to hear people describe fat as just melting away or vanishing, which doesn't encourage anyone to try to balance the books on where all those atoms actually go to, much less get them thinking in terms of their release as carbon dioxide and water vapor. The same problem persists in the language commonly used by biologists. We frequently refer to energy as "lost" when it's no longer available to an organism, but that doesn't mean it's not still there, typically in the form of heat.

The end result, the authors conclude, is that "faculty are unknowingly speaking a different language from their students." They think that when they mention lost energy, the students know what they're talking about, or that their students' poor choice of wording doesn't represent a failure of logic. As a result, they see little reason to speak more carefully or devote instructional time to clearing up misconceptions. And, even if they wanted to, most biology textbooks consider principle-based reasoning beyond their scope.

But, even if instructors and textbooks were ready, the limited improvements that resulted in the targeted interventions used in this study show that overcoming the tendency towards informal reasoning can be a significant challenge. And the authors don't necessarily know what to suggest beyond starting the process

Alpie, this might come as a surprise to you but during the night, the desert is freaking cold... Freezing-balls-off cold. EVERY night

[Al B. Sure!]

Night-time lows, N35t0r. The equivalent of one week with below freezing night-time lows. Only once was the daytime high below freezing.

I'd also like to point out that 7 of those 16 below freezing lows occurred in 2010. Global Warming

Only 15% of sampled days from 2009-2004 had below freezing lows.

[dannubis]

Yeah, evolution

Can you please post your Excel spreadsheet? Also, are their graphs?
