Fluid Flow & Equipment: Crash Course Engineering #13 Fluid Flow & Equipment: Crash Course Engineering #13
3 days ago En
Today we’ll dive further into fluid flow and how we can use equipment to apply our skills. We explain Bernoulli’s Principle and the relationship between speed and pressure in certain flowing fluids. We’ll also discuss how to apply the principle with Bernoulli’s Equation and try to use it in real-world examples.

T-Tests: A Matched Pair Made in Heaven: Crash Course Statistics #27 T-Tests: A Matched Pair Made in Heaven: Crash Course Statistics #27
3 days ago En
Today we're going to walk through a couple of statistical approaches to answer the question: "is coffee from the local cafe, Caf-fiend, better than that other cafe, The Blend Den?" We'll build a two sample t-test which will tell us how many standard errors away from the mean our observed difference is in our tasting experiment, and then we'll introduce a matched pair t-tests which allow us to remove variation in the experiment. All of these approaches rely on the test statistic framework we introduced last episode. Crash Course is on Patreon!

Test statistics allow us to quantify how close things are to our expectations or theories. Instead of going on our gut feelings, they allow us to add a little mathematical rigor when asking the question: “Is this random… or real?” Today, we’ll introduce some examples using both t-tests and z-tests and explain how critical values and p-values are different ways of telling us the same information.

3 weeks ago En
Today we’re going to talk about Bayes Theorem and Bayesian hypothesis testing. Bayesian methods like these are different from how we've been approaching statistics so far, because they allow us to update our beliefs as we gather new information - which is how we tend to think naturally about the world. And this can be a really powerful tool, since it allows us to incorporate both scientifically rigorous data AND our previous biases into our evolving opinions. CORRECTION: At 2:09 the righthand side of the equation should not have P()'s, it should just be the raw numbers. Crash Course is on Patreon!

The First & Zeroth Laws of Thermodynamics: Crash Course Engineering #9 The First & Zeroth Laws of Thermodynamics: Crash Course Engineering #9
1 month ago En
In today’s episode we’ll explore thermodynamics and some of the ways it shows up in our daily lives. We’ll learn the zeroth law of thermodynamics, what it means to reach a thermal equilibrium, and define the first law of thermodynamics. We’ll also explore how stationary, adiabatic, and isochoric processes can make our lives as engineers a little easier. Note: Different branches of engineering sometimes define the first law of thermodynamics differently, depending on how work is defined. Essentially, work released from a system might be defined as a positive value or a negative value, and thus the first law can be defined as either Q-W or Q+W. Both are acceptable forms, depending on how the system is defined! We chose to focus on only one definition here to limit the confusion.

P-Value Problems: Crash Course Statistics #22 P-Value Problems: Crash Course Statistics #22
1 month ago En
Last week we introduced p-values as a way to set a predetermined cutoff when testing if something seems unusual enough to reject our null hypothesis - that they are the same. But today we’re going to discuss some problems with the logic of p-values, how they are commonly misinterpreted, how p-values don’t give us exactly what we want to know, and how that cutoff is arbitrary - and arguably not stringent enough in some scenarios.

Rules, Rule-Breaking, and French Neoclassicism: Crash Course Theater #20 Rules, Rule-Breaking, and French Neoclassicism: Crash Course Theater #20
1 month ago En
Everyone knows, you need a bunch of rules to make good theater. That's what the French thought in the 17th century, anyway. The French Neoclassical revival had a BUNCH of French playwrights following a bunch of rules. Unsurprisingly, some of the most interesting plays of the era broke those rules. Today, we'll talk about the rules, and we'll talk about Racine (who followed them), and Corneille (who was not so much a rules guy). Crash Course is on Patreon!

How p-values help us test hypotheses: Crash Course Statistics #21 How p-values help us test hypotheses: Crash Course Statistics #21
1 month ago En
Today we're going to begin our three-part unit on p-values. In this episode we'll talk about Null Hypothesis Significance Testing (or NHST) which is a framework for comparing two sets of information. In NHST we assume that there is no difference between the two things we are observing and and use our p-value as a predetermined cutoff for if something seems sufficiently rare or not to allow us to reject that these two observations are the same. This p-value tells us if something is statistically significant, but as you'll see that doesn't necessarily mean the information is significant or meaningful to you. Crash Course is on Patreon!

EPISODE DESCRIPTION The English Theater survived a lot of pushback from various powers that be, but in the 17th century, it had to go into hiding, from PURITANS. Let's take a look at how the English Civil War, Charles I's beheading, and the Restoration of the monarchy all had effects on the English Theater. Also, not to bury the lede, but WOMEN finally make it to the English stage in this episode. Plus, Restoration comedies are pretty smutty, so you should hang on 'til the end of this one.

Confidence Intervals: Crash Course Statistics #20 Confidence Intervals: Crash Course Statistics #20

Today we’re going to talk about confidence intervals. Confidence intervals allow us to quantify our uncertainty, by allowing us to define a range of values for our predictions and assigning a likelihood that something falls within that range. And confidence intervals come up a lot like when you get delivery windows for packages, during elections when pollsters cite margin of errors, and we use them instinctively in everyday decisions. But confidence intervals also demonstrate the tradeoff of accuracy for precision - the greater our confidence, usually the less useful our range. Crash Course is on Patreon!

The Normal Distribution: Crash Course Statistics #19 The Normal Distribution: Crash Course Statistics #19
2 months ago En
Today is the day we finally talk about the normal distribution! The normal distribution is incredibly important in statistics because distributions of means are normally distributed even if populations aren't. We'll get into why this is so - due to the Central Limit Theorem - but it's useful because it allows us to make comparisons between different groups even if we don't know the underlying distribution of the population being studied.

The history of medicine is about two of our big questions: one, what is life? What makes it so special, so fragile, so… goopy!? Two, how do we know what we know? Why should I take my doctor’s advice? Why are deep-fried Oreos bad for me? It may be tempting to look at medicine as a science that has simply progressed over time—that medicine used to be bad, and its history is a story of how it got better. *** Crash Course is on Patreon!

Z-Scores and Percentiles: Crash Course Statistics #18 Z-Scores and Percentiles: Crash Course Statistics #18
2 months ago En
Today we’re going to talk about how we compare things that aren’t exactly the same - or aren’t measured in the same way. For example, if you wanted to know if a 1200 on the SAT is better than the 25 on the ACT. For this, we need to standardize our data using z-scores - which allow us to make comparisons between two sets of data as long as they’re normally distributed. We’ll also talk about converting these scores to percentiles and discuss how percentiles, though valuable, don’t actually tell us how “extreme” our data really is. Crash Course is on Patreon!

Shakespeare's tragedies...were tragic. But they had some jokes. They also changed the way tragedies were written. Characters like Hamlet, Macbeth, and King Lear had tragic outcomes, but they were sympathetic characters in a lot of ways. This was a big change from the way Seneca and the Greeks wrote tragedies, and it caught on. Crash Course is on Patreon!

There are a lot of events in life that we just can’t predict, but just because something is random doesn’t mean we don’t know or can’t learn anything about it. Today, we’re going to talk about how we can extract information from seemingly random events starting with the expected value or mean of a distribution and walking through the first four “moments” - the mean, variance, skewness, and kurtosis. Note: There are many formulas to calculate skewness and kurtosis (https://www.itl.nist.gov/div898/handbook/eda/section3/eda35b.htm), our formulas deal with what they have in common, their moment generating functions.

Geometric probabilities, and probabilities in general, allow us to guess how long we'll have to wait for something to happen. Today, we'll discuss how they can be used to figure out how many Bertie Bott's Every Flavour Beans you could eat before getting the dreaded vomit flavored bean, and how they can help us make decisions when there is a little uncertainty - like getting a Pikachu in a pack of Pokémon Cards! We'll finish off this unit on probability by taking a closer look at the Birthday Paradox (or birthday problem) which asks the question: how many people do you think need to be in a room for there to likely be a shared birthday?

The Medieval Islamicate World: Crash Course History of Science #7 The Medieval Islamicate World: Crash Course History of Science #7
3 months ago En
The religion of Islam significantly influenced knowledge-making in the greater Mediterranean and western Asian world. Islamicate scholars—meaning people influenced by Islamic civilization, regardless of their religious views—gave us terms such as “algebra,” “azimuth,” “algorithm,” “alcohol,” “alkali,” and “alembic.” We’ll dive into Islamic medicine and philosophers such as the great Persian polymath Ibn Sina in future episodes. For now, let’s explore the beginnings of Islamicate natural philosophy. It's really cool, you guys! *** Crash Course is on Patreon!

The English Renaissance and NOT Shakespeare: Crash Course Theater #13 The English Renaissance and NOT Shakespeare: Crash Course Theater #13
3 months ago En
The Renaissance came to England late, thanks to a Hundred Years War that ran long and lasted 116 years, and then a civil war to decide who would be the royal family. BUT after all that, with the Tudors (relatively) securely installed on the throne, there was a flowering of humanism, science, and culture. Theater was a big part of it. Today, we're talking about the London theater scene and the playwrights that set the stage...ahem...for the main man of English Theater, William Shakespeare. Crash Course is on Patreon!

The Binomial Distribution: Crash Course Statistics #15 The Binomial Distribution: Crash Course Statistics #15
3 months ago En
Today we're going to discuss the Binomial Distribution and a special case of this distribution known as a Bernoulli Distribution. The formulas that define these distributions provide us with shortcuts for calculating the probabilities of all kinds of events that happen in everyday life.They can can also be used to help us look at how probabilities are connected! For instance, knowing the chance of getting a flat tire today is useful, but knowing the likelihood of getting one this year, or in the next five years, may be more useful. And heads up, this episode is going to have a lot more equations than normal, but to sweeten the deal, we added zombies! If you want to try out some of the math from this video here is a great binomial probability calculator: http://vassarstats.net/textbook/ch5apx.html If you'd like more information on calculating the binomial coefficient (n-choose-k) read this: http://www.statisticshowto.com/binomial-coefficient/ Want to find Crash Course elsewhere on the internet?

The Romans developed a lot of infrastructure like roads and aqueducts to both help their cities flourish and to... you know... be better at war. But the interesting thing about Roman Engineering is how it was almost all focused on Techne and not Episteme. In this episode of Crash Course History of Science, Hank takes us down the road of road building, domes, and some really cool cement. *** Crash Course is on Patreon!

This week, we're going to Italy for a Renaissance. The Middle Ages are over, and it's time to talk about the flourishing of art and humanism across Europe. Painting, sculpture, music, architecture, and plays with fart jokes were all thriving between from 1300 - 1500, and we're going to teach you about the theatrical aspects of that flourishing, as it happened in Italy.
