That is why you use Statistical Process Control. I used to build assembly equipment and many tolerances were controlled by statistics. For eample say you had a certain diameter on a part that needed to be within tolerances. The first thing you do is take data on random parts to make sure all you have are random variations. If there is anything non-random you need to fix it. Then you set your control limits such that your process with your required degree of certainty is within it. So if you need the part to be from .998 to 1.001 you make sure your 3 sigma values are from .999 to 1.000. That way you can take random samples and make sure your process is in control in the limits. If your process degrades over time and you fall outside of those limits you are still making good parts you just know you need to replace tooling or perform maintainence to get the process back in control

So it's better they aren't hired at all?

If you set up a system where you can be sued for firing people if they belong to a certain group why be surprised when they are not hired in the first place? Let's say women from a particular college were likely to accuse you of rape if you broke up. How many dates would they get?

The same thing here. You need to be 100% sure you are picking the perfect protected employee because it will cost you plenty to fire them. Nobody is going to give someone a chance to prove themselves because it's too risky.

Get rid of these stupid laws and you could easily hire 100 kids out of less well known schools and keep the 5 or 10 best.

It was also used many times in the North when people were accused of harboring or helping fugitive slaves. The juries would refuse to convict.

Since we now have several million non-violent people rotting in prison maybe we should start using it again?

I think the real reason is the prison industrial complex doesn't like to be questioned. There is a lot of money at stake keeping those millions locked up.

I'm not sure about the UK but in the U.S. juries are kept mostly in the dark by the judge.

I was on a jury where the judge was the same one on the Zimmerman trial. In this case it wasn't clear what happened because every witness contradicted each other. The defendant seemed to claim self defense as in she said the other woman tried to hit her so she punched her in the face which left a bruise. The other woman claimed out of the blue the other woman hit her with an 18 in wrench. The defense attorney never made the self defense case which led me to believe the judge prevented him from doing so.

Being a troll in general when we were in deliberation I sent a note to the judge asking for a copy of Florida's law in self defense.(that was Zimmerman's claim). She called us back in and read the same exact jury instructions she read before.

It took me a while to talk the other jurors out of Assault with a weapon (since no weapon was ever found). I could not get them to understand there was reasonable doubt that the defendant was using self defense since the lawyer never argued it. They kept saying the judge told us to follow these instructions.

That way the just go collect the plastic and make more of themselves until the ocean is clean.

Of course we may run into the Slylandro problem.

You missed the important part. Detain for 4 hours " allowing law enforcement to arrive and evaluate the situation."

Whenever you use force you need to look at the unintended consequences. With a law like this people that might need help could stay away for fear of being detained while the doctors call the police.

If you are going to have democracy then you need to push things to the lowest level possible. Instead of 50% + 1 winning it needs to be more like 2 sigma or 95%. If you want to delegate a function to the national government then 95%+ of the people should agree. Same for the state, county, town, neighborhood, family, or individual. The system we have now insures conflict because you can force a slight majority to your will.

The problem is as follows. Employees like every producer want to have very few competitors, be able to charge a high price, and have steady predicable income. But as consumers we want the opposite. We want lots of choices, low prices, and be able to change the provider of our goods and services at whim. These are directly opposed.

If your policies favor the former you will get a market with a few, expensive, and slow changing products and services. If you favor the latter you will have a market with plenty of cheap and ever evolving products to meet consumers demands.

The goal of all lobbyists is to favor the former for their particular company or industry while favoring the latter for the rest of the economy.

when I was about 12 in the mid 80's I rode my bike 10 miles to Radio Shack and bought all of the Mercury Switches they had (4?) for about $1.50 each. I built people detectors which consisted of a copper tube with batteries, Mercury switch, on/off push button, and siren. When we played hide and seek or paintball I could arm one and put a string across a path. If someone hit the string the siren would go off.

I lost one or so I thought. A kid found one and took it home. His Mom called the cops because she thought it was a bomb. The kid ratted me out as the builder. The cop showed up at my house and asked me to come look at something. I followed him and one of these devices was in the street. I told the cop what it was and he laughed and told me to pick it up and take it home.

I can't imagine what would happen today.

I've designed many gear trains for various devices. The reason this is useless is because you can't drive anything with it.

Harmonic Drives have been around a long time. https://en.wikipedia.org/wiki/...

The problem when you couple them together is you get more torque then the teeth can handle.

The reason most gear trains are larger is because you are typically trying to do something useful like taking a small high speed motor and using the gears for a high torque low speed application. This requires large gear teeth to handle the stresses.

This is like a kid building a bridge with Popsicle sticks. Cool but completely useless.

Most likely not. For consitency they are going to most likely use synthetic fertilizers. I highly doubt they are going to be using compost tea.

If you even work with Liquid Hydrogen you can actually condense Liquid Oxygen out of the air. If it drips onto asphalt it can light it on fire just from the impact.

I don't see how a PID controller will help much. You are cooking with very low temperature air (around 200 F). You have this massive ceramic cooker with large heat capacity. It's not a process that is going to run away from you even if you used a simple on/off controller.

The most important thing for good BBQ is picking a good cut of meat. Do that right and you can throw it in your oven and it will be delicious.

“Mechanical engineers, it’s not a required class for them,” says bioengineering major Jordan DeGraaf. “There are no mechanical engineers who take this class. They just run away.”

This class is a ME for Non ME's. Everything in this project/class is what is the core of what ME is. Fluid Flow, Heat Transfer, Sensors, Controls, Materials, etc. I'm guessing the reason there are no ME's in it is because they are taking the real ME classes.

This is similar to when I was in school for ME but I had to take one EE class for non EE majors. There were no EE's in there not because it was hard but because it was easy.
