A Call To Action – Sack John Horgan

I recently discovered from the mindweapon blog that Scientific American is allowing one of their writers John Horgan to use the Scientific American blog as a platform to call for the banning of race and IQ research.

I don’t have to explain to anyone with even the most superficial scientific interest why a blogger who advocates the banning of any kind of research does not belong at a science magazine.

We have long been far too tolerant.  When Derbyshire or Richwine make even the most tame and substantiated factual statement they lose their job.

We allow the most egregious anti-scientific garbage to slip past us and we do nothing.

I therefore call on our readers and all concerned citizens to do the following:

1.) Spread this message around the internet.

2.) Contact anyone you know that subscribe to Scientific American and ask them to cancel their subscription and instead subscribe to Nature (a better science journal).  If you can afford it, pay for their Nature subscription yourself.

3.) Contact the editorial staff, the publisher, and the advertisers of Scientific American and demand an apology AND THE PERMANENT REMOVAL OF JOHN HORGAN from the Scientific American blog and magazine.

Let the corporate offices of their advertisers know that you will not purchase their products and will tell all of your friends and family to avoid their products as well.

Don’t comment on Horgan’s blog or call him or write to him.  He’s a radical fanatic.  He doesn’t care what you say.

Contact his employers.

There are millions of us around the world and hundreds of thousands of us in the US alone.  Our friends and family make our effects exponential.

Wnthinktank and mindweaponsinragnarok are united in this call. If you are a blogger join this movement.

Readers can begin by writing the editors of Scientific American at:

editors@sciam.com

Let them know that you are contacting their advertisers. Don’t waste your time on ideas. They don’t care. They care about advertising dollars, not your scientific opinions.

Don’t sit back and accept this!

MIT Circuits and Electronics Lecture 15B

Overview
Today’s lecture is 50 minutes long. It looks like the alternative

version of lecture 15, which everything done on powerpoint. This

lecture was recorded in 2003. They took pains to blank-out the exact

URL of the simulator he quoted. He has been teaching this class for at

least 5 years.

Details
We can speed up the charging of the capacitor by reducing the resistor

R. ZSR is the initial condition of no voltage and no current in either

the inductor or capacitor.

The capacitor of the LC circuit will have a voltage of over the input

voltage. This is found in DC to DC converters.

Adding R will help a sinuside decay to zero.

VL=L di/dt
IC=C dv/dt

THe teacher describes a trick used by Richard Feynman. He would apply a

simple case to a proof presented and show up everyone else there.

Feynman had a need to be the smartest person in the room, or at least to

be percieved that way.

“Just imagine the R is a dollar sign, $$$. Follow it.” He negs the

class a little bit.

s2 + Rs/L + 1/LC=0 is the characteristic equation
s2 + 2as + wo2 = 0

Euler relation e^jx = cosx + jsinx

Scaled sum of sines. If you have a bunch of sine waves, you can add

them up in some way to get another sine wave.

“Konquer it like Kolodziejski.”

Q is appromiataly the number of cycles of ringing. High Q, many cycles.

Initially, we start at Vo. After a long time, the input appears across

the capacitor. Thus we have the final and initial conditions.

MIT Circuits and Electronics Lecture 15: Second Order Systems

Overview
Today’s lecture is 50 minutes.

Details

For inductors, the state variable is the current. For capacitors, the state variable is the voltage.

Second order systems have two independent storage elements. Often at transitions, you’ll see spikes. Those are actually decaying sinusidals.

Reducing the resistance in an RC circuit will lower the time constant, making the voltage rise faster.

Current flowing through a loop creates an inductance. It can be modeled by throwing an inductor in series. Every wire has an inductance. Like a series RLC.

Experts tend to do things very simply. We’ll use a LC series circuit. Use the node method.

Element laws:
I=C dv/dt
V=L dI/dt
…this is something to be memorized.

1/L (Vi-v)dt INT = c dv/dt
1/L (vi-v)=Cd2V/dt2

LC d2v/dt2 + v = vi
solve using method of homogeneous and particular solutions.

The ZSR or zero state response is vo=0 and io=0. The characteristic equation is s2=-1/LC.

Euler relation: e^(jx) = cos x + j sin x.

KVL must hold at all times. We hit a series voltage LC with a step input. The voltage across a cap cannot change instananeously, so the entire voltage appears across the coil. Inductors love to hold currents, caps love to hold voltages.

MIT Circuits and Electronics Lecture 14: DRAM

Overview
The usual! Today’s lecture will cost you 48 minutes. We’ve got a sub
today, he sounds like a beaner. Hey mang!

Details
Vc(t) = Vi final + (Vc initial – Vc final) e^(-t/RC)

The DRAM chip is the dynamic random access memory element. A state is

stored as long as power is supplied.

The value of Vi only matters at t=0. We don’t care what happens before

then. The state of a cap is the summary of all inputs. The state

variable, what is stored on the cap is the charge.

Vc future = f(initial value, vi(t))

All past inputs at t> RonC. Often Ron <> Rl, T>>T without

buffer. Typically Rin = 1 Gohm, C=1 fF to 1 pF, thus RC = 1ms to 1 st,

we’d prefer a ms.

Time Management

In my article entitled “The New Man” I explained the necessity of the modern man to eliminate wasted or “free” time.  Many of us have no experience with this sort of thing and simply don’t know how.  In the age of smart phones, this is especially easy.  I taught myself before the age of smart phones and it took a considerable amount of effort, but was still achievable.

So, I will begin by writing a simple example schedule.  Keep your smart phone by your bed.  When you wake up in the morning, start playing a lecture from youtube.  Some of the major universities in the country offer their classes free of charge.  Have a set of computer speakers hooked up to your smart phone so that you can move around and still hear.  In this way you can virtually attend university level classes while you are getting dressed, eating and so on.  That’s 1-2 hours of lecture per day.

You can listen to lectures with ear buds as you walk to your car.  Plug the phone into your stereo and listen to them as you drive.  That’s another hour of lecture per day, totaling three hours per day without changing your schedule.

If you have a job that is mindlessly repetitive, you can listen to lectures all day while you work.  If not, you certainly can while you are eating your lunch and break.  That’s another hour per day.  So far, we’re up to 4 hours without changing our schedule one bit.

When you get home, keep listening as you eat dinner, do chores and listen as you lie in bed until you fall asleep.

In this way, not a moment is lost.  Every available minute, you are learning something new and completing classes.

When you have free time and can view the screen and chalkboard of the class, you should concentrate on science.  When you are walking, driving or something else, you should listen to history lectures because your eyes are not required.

In the last year and a half, I have completed the following classes without altering my daily schedule:

Integrative Biology 131 uc Berkeley

General Biology 1a uc Berkeley

Chemistry 1a uc Berkeley

History of the World to 1500 CE Columbia University

History 5 UC Berkeley European civilization from the renaissance to the present

History 210 the early middle ages 284-1000 yale

African American History yale

Introduction to Chemical Engineering Stanford

That is a full university load for over a year without changing my schedule, while others are watching television or playing video games or listening to repetitive music or reading redundant blog posts about issues they already know.

That is only one year.  I’ve been doing this for the last twenty five years and will continue to do it for the rest of my life.

This is not to boast.  This is just to show you what is possible and how much of your life is being wasted in idleness.

A year and a half ago, we began doing these group science study classes at this site.  If you had followed along with us, for just 50 minutes per day, you would now know a ton of Chemistry, Biology, Anatomy, Medicine, Physics, Electricity and a lot more.

This would’ve only meant cutting out one television program or one blog per day.  You’d have a year out of a science degree completed.

What did you accomplish last year?

Today is a new day. 

Rethink your priorities. 

Don’t make the same mistake this year as you made last year. 

Next year you could look back proudly as you see what you have achieved. 

Stop being lazy! 

Join us!

MIT Electronics and Circuits Lecture 13: Time Delay

Overview
Today continues our mini-series on capacitors. This lecture will

cost about 50 minutes, the usual. The teacher’s usual outfit is

a blue short sleeved shirt with no tie, a belt, and white khakis.

Details
The canonical circuit is a voltage source in series with a

resistor and a capacitor. We assume Vi > Vo. If we switch the

circuit on, eventually the input voltage vi will appear on the

cap. He likes the “Bend it like Beckham” approach, using

instinct.

The intuitive approach:
After a long period of time, Vi appears across the cap. Vo is

the initial voltage on the cap. We know the form and we fit an

equation to it.
Vc = [Vo +(Vi-Vo)](1-e^(-t/RC))

If Vi<Vo,
Vc = Vi +(Vo-Vi) e^(-t/RC)

At what point is a rising exponential a logical 1? When V

reaches VOH. The rising delay of X. If the cap is zero, then an

instantaneous transition.

Rise Time = Tr = -RL Cgs ln (1-Voh/Vs)
Cgs = 0.1 pf or "puff"
Rl Cgs = 0.1 ns

The falling delay circuit is a voltage source, voltage divider

with a cap in parallel.

R th = R1R2/(R1+ R2)
V th = Vin R2/(R1+R2)
Rth Vgs = 1 ps

Sometimes slower transitions are necessary to get rid of

transients. In one case, they use a triangle wave versus a usual

square wave.
