Out of Math and Physics is History...

Looking back over some old bookmarks, I came across this.

It is good to remember when there were times that large groups of people got along.  Here is one person's view of such times for us to consider when deciding how to react rationally to world events:
As you know, Islamic civilizations rise in the 7th century, and start to fall dramatically in the 14th century for many reasons.

When we discuss the history of this civilization, you could understand that fact.

Before start to talk about contribution of Islamic civilization in human civilization, I would like to present some historical facts, also some ‘’western’’ references:

Here are some interested points:

- Baghdad was the center of the world in the 9th century. It population around two millions.

- The first translation university was built in Baghdad in the 9th century. It was called (Dar Al Hikmah) or Wisdom House. They translated hundred thousands of Greek, Persian, Roman, Hebrew, and Indian documents and books to Arabic.

- For the first time, Jews, Muslims and Christian succeeded to live in peace in liberal (semi democratic society) in Spain in the 10th century.

- Many schools of laws were established in 11th and 12 century.

- The largest Islamic State is Indonesia (20% of Muslims in the world), no Islamic army reached this State. The people converted to Islam due to economical relations, the same as Malaysia and SE Asia.

The collapse of Islamic civilization could be concluded by these reasons:

- Crusaders wars: 200 years of religious catholic wars against Muslims, Jews and orthodox Christian. These wars exhausted the ME societies.

- Mongolian wars: Before the end of crusaders wars, Mongolian invaded the East. They destroyed Baghdad, killed 800000 people and burn its well known library.

- Fall of Spain: Muslims lost Spain in the end of 15th after 800 years of great civilization. Spanish changed the trading from ME to South Africa, which had great economical impact.

- Islamic scholars stopped developing the laws since 14 century, which made many of them not suitable for modern societies.

- Ottoman Empire, ruled the Islamic world recently. They involved in many wars with Russia, Romania, Balkan, Greece, UK, France , Egypt … which converted it to military State.

Islamic civilization and Science

Specific Muslims scientists and their contribution in human civilization:

- Alhazen, is considered as the father of modern Optics:

About 810
House of Wisdom set up in Baghdad. There Greek and Indian mathematical and astronomy works are translated into Arabic.

About 810
Al-Khwarizmi writes important works on arithmetic, algebra, geography, and astronomy. In particular Hisab al-jabr w'al-muqabala (Calculation by Completion and Balancing), gives us the word "algebra", from "al-jabr". From al-Khwarizmi's name, as a consequence of his arithmetic book, comes the word "algorithm".

About 850
Thabit ibn Qurra makes important mathematical discoveries such as the extension of the concept of number to (positive) real numbers, integral calculus, theorems in spherical trigonometry, analytic geometry, and non-euclidean geometry.

About 850
Thabit ibn Qurra writes Book on the determination of amicable numbers which contains general methods to construct amicable numbers. He knows the pair of amicable numbers 17296, 18416.
About 900
Abu Kamil writes Book on algebra which studies applications of algebra to geometrical problems. It will be the book on which Fibonacci will base his works.

920
Al-Battani writes Kitab al-Zij a major work on astronomy in 57 chapters. It contains advances in trigonometry. 
About 960
Al-Uqlidisi writes Kitab al-fusul fi al-hisab al-Hindi which is the earliest surviving book that presents the Hindu system.

About 970
Abu'l-Wafa invents the wall quadrant for the accurate measurement of the declination of stars in the sky. He writes important books on arithmetic and geometric constructions. He introduces the tangent function and produces improved methods of calculating trigonometric tables.

976
Codex Vigilanus copied in Spain. Contains the first evidence of decimal numbers in Europe.
About 990
Al-Karaji writes Al-Fakhri in Baghdad which develops algebra. He gives Pascal's triangle.

About 1000
Ibn al-Haytham (often called Alhazen) writes works on optics, including a theory of light and a theory of vision, astronomy, and mathematics, including geometry and number theory. He gives Alhazen's problem: Given a light source and a spherical mirror, find the point on the mirror were the light will be reflected to the eye of an observer.

About 1010
Al-Biruni writes on many scientific topics. His work on mathematics covers arithmetic, summation of series, combinatorial analysis, the rule of three, irrational numbers, ratio theory, algebraic definitions, method of solving algebraic equations, geometry, Archimedes' theorems, trisection of the angle and other problems which cannot be solved with ruler and compass alone, conic sections, stereometry, stereographic projection, trigonometry, the sine theorem in the plane, and solving spherical triangles.

About 1020
Ibn Sina (usually called Avicenna) writes on philosophy, medicine, psychology, geology, mathematics, astronomy, and logic. His important mathematical work Kitab al-Shifa' (The Book of Healing) divides mathematics into four major topics, geometry, astronomy, arithmetic, and music.

1040
Ahmad al-Nasawi writes al-Muqni'fi al-Hisab al-Hindi which studies four different number systems. He explains the operations of arithmetic, particularly taking square and cube roots in each system.

1072
Al-Khayyami (usually known as Omar Khayyam) writes Treatise on Demonstration of Problems of Algebra which contains a complete classification of cubic equations with geometric solutions found by means of intersecting conic sections. He measures the length of the year to be 365.24219858156 days, a remarkably accurate result.

1130
Jabir ibn Aflah writes works on mathematics which, although not as good as many other Arabic works, are important since they will be translated into Latin and become available to European mathematicians.

1142
Adelard of Bath produces two or three translations of Euclid's Elements from Arabic.

1149
Al-Samawal writes al-Bahir fi'l-jabr (The brilliant in algebra). He develops algebra with polynomials using negative powers and zero. He solves quadratic equations, sums the squares of the first n natural numbers, and looks at combinatorial problems.

1150
Arabic numerals are introduced into Europe with Gherard of Cremona's translation of Ptolemy's Almagest. The name of the "sine" function comes from this translation.

1411
Al-Kashi writes Compendium of the Science of Astronomy.

1424
Al-Kashi writes Treatise on the Circumference giving a remarkably good approximation to  in both sexagesimal and decimal forms.

1427
Al-Kashi completes The Key to Arithmetic containing work of great depth on decimal fractions. It applies arithmetical and algebraic methods to the solution of various problems, including several geometric ones and is one of the best textbooks in the whole of medieval literature.

Can we see how it is one species here and not groups partitioned by political boundaries?

Let's hope we do this right and not jump back into recent derogatory quarrels that get us nowhere.

A Voice Like No Other

I'm sure I once described to you a voice that appeals to me like no other.

Sure, my wife's voice is one of the voices I think of most.

But there's another, a person who has stood near me, singing, smiling, laughing, carrying on as if we're all hanging out at a family reunion.

She knows who I'm talking about.

But she doesn't know me and I don't know her.

How do I describe the voice without describing the voice?

She doesn't sing opera but she could sing at the Grand Ole Opry.

She doesn't sing rap but her wordplay is just as entertaining as an rapper's.

She defied the system and took a break to raise a family.

I still remember the first time I heard her like some say they remember the first time they heard Elvis.

Sitting in the carpark of a bowling alley, listening to the radio, waiting for my wife and bowling partners to show up.

Seems like a pretty appropriate place, there in Rocket City, a few miles from rocket test stands and torndown cotton mills.

Might have been sitting in the old four-dour Chevy Nova that had gone on more offroad adventures than the Ford Ranger I owned later.

They say Alison Kraus has a voice of gold but she pales in comparison to the refrain of real life pouring out of the heart and soul of Claire Lynch.

Will I ever know Claire or she know me?

Probably not.

I can't sing along with a karaoke machine, let alone a versatile performer like Claire, who jumps from bluegrass to swing with the ease of a chickadee flying through a Southern breeze bending trees and freezing bees.

Love life 'cause it's all we've got.

Sing and dance 'cause this is the only moment we know we'll ever have.

Claire, here's to you, young gal.  May that voice of yours last forever, or at least as long as I'm alive and can still hear!  ;)

Land of the Dancing Rabbits

This time of year I enjoy (surprised more than look forward to seeing) maple trees in the lower canopy that stick out because of their manila, beige, rust-coloured leaves that haven't escaped into the new life of loam and humus.

So much so that words have no meaning to me today except for their ability to hold my attention temporarily, placeholders, fish hooks holding on to the flesh of thoughts and ideas in the states of energy that I think are me.

This planet feels tiny.

Miniscule.

All of our actions easily forgotten in the flash of a supernova or the smaller crash of solar storms against our thin atmosphere.

Those who control those who control the Committee have asked me to demonstrate powers that I have no idea what they're talking about.

Does a prism have powers?

Can a funhouse mirror change the future by changing the direction of lightwaveparticles?

Can the graceful movements of tai chi create freedom of choice in a people trapped in thought and body for generations?

Would an Ulster Scot bring Catholics, Protestants, Muslims and Jews to the same table, with Hindus and Buddhists working to eliminate the worthless emotional teachings of history so the remaining groups of emotion-based believers could join while still respecting life-affirming [sub]cultural differences?

Can you take off fear like a ragged old coat that no longer fits and needs to be churned into the compost bin?

Sitting on this mountaintop of solid-rock thought sets, looking across the valleys to titans sitting on top of piles of imaginary power in the form of money, religion, athletic skill and/or physical beauty, I rest assured that the two in the know are comfortably being told what to do with their free will.

Sure, history is being made, but who's going to write it?

If death is still death, does it matter whether a person died of torture, starvation or complications during life-extending genetic modification?

I still plan to see Earth onboard a Moon cruise ship.

I still believe we will overcome the insanity of crazed salespeople shoving stopgap measures down our throats because there's nothing else more lucrative to market to the masses.

But I am not important.

Something greater than me is.

Greater than all of us put together.

We are one point - the billions of years that led up to our existence right now - on a spiral that's designed for achieving movement by what we call the unknown.

We can't get out of our point if we can't see the point we're making.

Those who are entrenched or have vested interests will not understand, but you already know that through your subcultural training.

Have you held a mirror up to yourself to see the miniscule difference that divides you from the rest of the members of our species and the rest of the living things on Earth?

How far have you projected your thought set into the universe as you know it?

Do galaxies and superclusters act as memory locations for you?

What about the parts that you can't see but imagine are there?  Have you absorbed them into your extension of self?

Does it matter if the Sun acts as a memory location for trillions of living things?

If a memory is just another interaction of states of energy, what does that say about your place in the global ecosystem?

Do you still want to own the company that depends on motivating millions of people to desire a nonessential consumable that has many in/direct negative effects on your children and the children of people and living things you don't know?

What is profit, really?

Are you willing to move your company's growth slowly enough to ensure you're benefiting more than a few people in the moment?

How do we have fun and not think about these "serious" issues in our momentary, blissful forgetfulness?

Your random acts and purposeful goals are not mine but our behaviours all belong to the set of steps to achieve goals you and I will never know about.

That's why I don't worry about which empire is collapsing and which empire is secretly financing an empire it will soon absorb into its own.

None of those matter to me.

Freedom at the individual level is all I need to measure to determine what will happen next to see which 1000-year projection it best lines up with.

After a while, the wave patterns of a planet are easy to predict, throwing out whole classes of waves that intersect and cancel each other out.

The planet is a small part of other wave interactions, some which add, some which subtract and some which cancel each other out.

At the multiuniverse level, we've already predicted which ones will cancel each other out and have discounted them from our future projections.

Do you understand what I'm saying?

Probably not.

Rare is the individual who can see 100,000, 1,000,000, or 1,000,000,000 years into the future.

Death is such a large event in our lives that we barely look past the end of our noses or maybe just as far as the reflection in the mirror.

We just want to know how we're going to put food in our mouths in the next few hours and find a decent way to take care of our families.

As usual, that's okay.

That's what we want you to want.

Which is more important to you - a diamond ring or freeing and feeding the child slaves who work the diamond mines?

You don't have to answer.  Your behaviour patterns have already answered the question for us.

My grandfather always said that electricity and indoor plumbing would ruin us because we can't see where it's coming from and where it's going.  He was a lot more succinct than I am.

We're such a young species, it hurts to watch our ignorance get the best of us.

Think I'll shut this down and drink a few beers to put myself in a mood of forgetfulness with everyone else.

There are no easy questions but the answers are easier than we think if we take time to think in between our rushes from one activity to another that we try to squeeze in before we die individually, assuming we care to take responsibility for the effect of our actions on others outside the thought set of whose job and company we're helping to succeed.

Enough of this lecture to self.  Time to relax.

Do You Know Who's Watching Your Back?

Another review.

The oldest woman in the world and I have something in common.

But I don't know what she'd think about this.

At the end of 2010, I decided to stop taking medicine that's supposed to control my blood pressure and cholesterol.

For the past few years, I have felt my self-esteem decrease and watched my weight increase as I fell into the trap of using chemical compounds to overcome my genetic tendency to live only into the 60s or 70s.

After I stopped taking the medicine, an imaginary cloud lifted and blew away, my thoughts cleared and I've lost 15 pounds of body weight.

I'm no Luddite but I'm also a skeptic when it comes to the miracles promised by new technology.

I am happy being a naturally-aging man past the midpoint of his life.

Sure, I use a computer and eat food that's supposed to be good for me but I also drink fermented beverages and occasionally eat fried, processed foods.

One of the many luxuries of a childless adulthood is feeling no guilty responsibility for my health and having no desire to see my great, great-grandchildren at birth.

So, I speak only for myself in this blog entry.

Happiness, for me, is popping no more pills day and night, having oatmeal and tea for breakfast, and then letting the rest of the day be what it may, including a random walk every now and then.

I am a new man, thanks to the freedom from nonaddictive drug dependency.

No more ARBs, statins or beta blockers for me.

No need to use my discretionary funds to subsidise the elixir industry.

This confession feels good.  I've never attended an LPDA (Legal Prescription Drugs Anonymous) meeting but this feels like I just did.

"Hi, my name is Rick and I'm a recovering LPD user."

"Welcome, Rick!" shouts the chorus.

I nod and smile.  A group of strangers just accepted me for who I am.

Doesn't get much more simpler and honest than that.

"Hey, guys, the pub's open.  Drinks are on me!"

USDA Denies It's Deliberately Poisoning Illegal Aliens

Did you know the USDA will poison any group of animals you ask it to?  Test it out and see for yourself.

"This is the USDA.  May I help you?"

"This isn't the Highway Department?"

"That's right."

"You mean it is."

"It isn't, you are correct."

"Well, I was wondering what you were going to do about the blacktop that is crumbling in this weather."

"I'm sorry, the connection is poor.  Did you say you have black birds that are eating crumbs in this weather?"

"That's right.  You're tearing up the asphalt with all the corrosive salt you all are pouring."

"Did you say we're bearing fault for not correcting while it's snowing?"

"Yes, and that stuff'll poison the grass."

"Oh, no.  It only poisons the birds."

"Well, doesn't that bother you?"

"Why should it?  It's our job.  Do you want us to come out there or not?"

"Are you going to repave the roads in this weather?"

"Oh, we'll repair your problem all right.  The roads will be clear in a matter of days."

"Sounds good to me."

"If you hear about any dead black birds, just tell them you sent for the USDA to take care of your problem."

"Seems extreme to me, but if that's what it takes to fix the roads these days, you do what you gotta do."

"We're here to serve the taxpayers.  Have a good day."

"You, too.  Thanks!"

It's Fun To Promote Fun

Another email, containing news about swing dancing for those of you who know how to have a good time exercising with your favorite person:

As most of you know, Jason and I [Danielle] just got done running a large swing event here in town; well, because of that we got featured in the Huntsville Times. If you would like to see the article, here is the link to it online.
http://blog.al.com/entertainment-times/2011/01/lindy_hop_anyone.html

Fun things for you:

The Gap commercial that came out a while back actually caused a roll in of new interest in swing dance at that time. Here is a video of it.

Some Awesome Charleston
http://www.youtube.com/watch?v=cY7QtPHo6M8&feature=related

Herrang Dance Camp is the largest swing dance camp in the world and it's in Sweden. Jason and I have been there twice and it's an amazing experience. So if you are ever interested in going to Sweden in the summer you really need to make a stop here. This is just one example of the craziness that goes on.

A much better version of the Stockholm Syndrome, I'm sure.


Have a great day!

More great news for search engine purists


Every great tester knows that boundary conditions, though well-defined in specifications or work orders, rarely are what they seem until you test, test, test.  They still confound you at the most inconvenient times, preferably not in a life-threatening situation, but it has and does happen anyway.

You could say the same about letting speculators drive up the cost of commodities with no connection to the "reality" (or realty) of supply and demand.  As an easy example, the price of oil should be tied to current/future supplies, with brakes or limits that prevent false bubbles (which, on a side note, would prevent conglomerates with financial subsidiaries from padding quarterly statements to hide or diminish the poor performance of their hard/soft product divisions).

The same goes for search engines, as well-documented in the email copied below:
The Weekly Feed #55: Google Heavily Penalizes Websites, Great Nutrition for your Blog Visitors and Speak2Tweet for Egyptians

Tue, Feb 01, 2011 1:18 am
Welcome to Issue #55 of The Weekly Feed. If this email was forwarded to you by a friend, you can subscribe on this page. The Weekly Feed is published once a week when we have news, information and helpful tips to share. Unsubscribe instructions are at the end of this message. You can read previous editions of The Weekly Feed on our blog where we may also post additional content.

Our site of the week is the awesome Nutrition search engine SkipThePie.org that gives you your very own nutrition search widget for your blog's sidebar. Visitors can get detailed nutrition data without leaving your blog. I've already put it on my personal blog so that I can look up calories before I eat them - and hopefully it helps a few of my visitors stay in shape too.

Three days ago Google launched and update that may radically affect the amount of search engine traffic your blog or website gets. They're calling it a minor update to their algorithm, but it has already had a major effect on some sites. 8 Days ago I mentioned on Hacker News that a site that was scraping the popular StackOverflow was ranking higher than them - by republishing their content. Well Google has updated their algorithm and the scraper site's traffic immediately plummeted by about 90%. The day-over-day drop is 40%. I'm not a fan of sites that steal content, but ouch!!

Here is Matt Cutts, head of Google's anti-spam team making the announcement a few days ago.

From industry buzz it seems that Google is going after two kinds of sites this year. The first is sites that scrape content from others and republish that content unmodified (scraper sites). The second is sites who have low quality content farms, where large numbers of low wage humans generate low quality content purely to try and attract search engine traffic. We've now seen hard evidence of the new anti-scraper policy but not much evidence of Google going after content farms. 

If you run a blog or content site that relies on SEO traffic, here is how you need to react to this:
  1. Make sure you limit the amount of republished content.
  2. If you do republish content, make sure there is at least the same amount of original content on the same page to balance it out.
  3. Beware publishing large amounts of low quality content. We haven't seen any evidence of penalties in this area yet, but trust me they're coming. 
I'm also modifying my back-link strategy slightly:

Google has always had a duplicate content penalty but over the last few years scrapers have gotten good at getting around that by mixing and matching content and adding just enough of their own to have it appear unique to a machine. Now Google have made a few additional changes to their search algorithm to penalize scraper sites. The question is, what changes did they make?  

My guess is that one of the things they are looking at is the number of "deep links" you have from other websites linking to content deep in your own site. Sites that scrape content tend to have many links from high ranking sites to their home page but few links to content deep in the site because people just don't find the content valuable enough.

So one of the ways I'm reacting to this algorithm change is to make sure that it's not just our home page that is linked to, but pages deep within the site too.

Expect to see a few more changes from Google like this as the year progresses. Remember, the most important thing is to have unique and useful content and to let the right websites know about it. 

Lastly, Google just launched a service that you'll hear about in the news tomorrow to help Egyptians stay in touch with the rest of the world as the government there removes Internet and Cellphone access. It's called Speak2Tweet and it's a collaboration between Twitter and Google. Here's the quote from Google's Blog in case you don't have web access and are in Egypt:

"It’s already live and anyone can tweet by simply leaving a voicemail on one of these international phone numbers (+16504194196 or +390662207294 or +97316199855) and the service will instantly tweet the message using the hashtag #egypt. No Internet connection is required. People can listen to the messages by dialing the same phone numbers or going to twitter.com/speak2tweet."

There are already some incredible messages being posted by Egyptians including this one referring to the million person march planned for tomorrow.

On a personal note, having lived through the transition of South Africa to a democracy, I'd like to wish any Egyptians who are Weekly Feed subscribers or Feedjit members a safe and influential week!
