Significant Figures: The Lives and Work of Great Mathematicians
Audiobooklife rating: 🤠🤠🤠🤠
This audio book was almost twelve hours in duration. Took me less than two days. The progression of math has been well studied and documented throughout history. It’s unbelievable we are able to follow it in such detail. Put me in a good mood. Quarantine has given me time to reflect and bulldoze digital audio books. What are you reading or listening to while being quarantined? Reading is therapeutic and helps make the state of affairs less painful and the sky more blue. 😀
Anyways the author is an acclaimed mathematician, a science fiction writer and Emeritus professor at Warwick in England. Math can be an intimidating and exigent subject. He makes the subject matter understandable and oh so enjoyable! It spans two-thousand years and touches on twenty five mathematicians through short biography. It’s a wonderful compendium of great minds that have discovered and created systems of math used today. None of which are alive. Shout out📢 to all living amateur and professional mathematicians! From the great geometer to the creation of algebra to the advent of super computers this book has it. There was even a chapter on Benoit Mandelbrot and fractal geometry. I love fractals! Nature is full of fractals. They are never ending patterns and you are free to get lost in them. ∛
I have a profound reverence for math myself. Everything in the universe obeys geometric rules and ratios. Through logic and deduction you can reduce all phenomenon in nature to mathematical axioms and laws. Also being a science major I had to reach at least the level of calculus. Why? Calculus was required for genetics. Genetics was required for cell biology. Cell biology was required for biochemistry. You get the idea. I spent many semesters in math class and we are well acquainted. ∞
My favorite mathematician would have to be Muhammad ibn Musa al-Khwarizmi. He is the father of algebra and the word algorithm derives from his manuscripts (see The Sieve of Eratosthenes). His work helped society get wages and inheritances properly and was one of the most famous scholars in The House of Wisdom. So much science and math were discovered in the ancient middle east. Pretty incredible! I guess that is one defining characteristic of people. The quest for knowledge, insight, understanding and awareness. Of course, Issac Newton (co-inventor of calculus) will always hold a special place in my heart. ∫
A little side joke. How would you define a significant figure? Google defines it as: each of the digits of a number that are used to express it to the required degree of accuracy, starting from the first nonzero digit. In a nutshell “Sig figs” are used in science and medicine to estimate how many decimal places are needed. 😆
Number is the ruler of all forms!

This wonderful audio book is just shy of eight hours. It took me a day then I listened to it again, believe it or not. It is available through RB Digital. I really enjoyed this book because it covers one of my favorite topics: counterinsurgency. It was a great autobiography of the author and an intimate view inside two of the more recent American wars, both taking place in Iraq: Operation Desert Storm and Operation Iraqi Freedom. All in all he is one of my favorite authors.
John Nagl is a retired Lieutenant Colonel from the US Army, is a graduate of West Point, earned a PhD from Oxford in Counterinsurgency (his thesis was turned into a book), the former president of CNAS (Center for New American Security) and is currently headmaster of the Haverford School in Pennsylvania. He is an excellent writer and has the ability to convey the harsh lessons of insurgency warfare (such as the Vietnam war). He makes the material enjoyable, intriguing and kind of makes you wonder what our top military brass was thinking at times when it came to their approach to military conflict.
LTC John Nagl and Gen David Petraeus
Being an Army tank commander in Desert Storm and an operations officer with the 1st Infantry Division in Operation Iraqi Freedom (OIF) he offers an intimate view of two technologically different combat zones. I liked the story from Desert Storm when he was awoke by a rocket barrage and said he thought rockets were going off on his chest.
His experience while stationed near Khalidiyah in OIF demonstrated to him that the days of conventional warfare are virtually over or at least not the case in this conflict. Insurgency warfare is the future of combat, we need to address it and take a new approach to how we conduct our war maneuvers in the Iraq and Afghanistan conflicts. So he was tasked co-authoring the book on counterinsurgency warfare while in the midst of these conflicts. This became FM 3-24: the US Army/Marine Corps Counterinsurgency Field Manuel, 2006.
I can attest to how poorly OIF was planned and executed. My Quarter Master Company was deployed to Iraq and after a couple months shuffling around country were stationed in Mosul. It felt like there was no plan after the three week long war was over. We were so amped up that we had just won a war in less than a month but nobody knew what the next step was so we just kinda hung out.
The situation was made worse due to the fact that the Iraqi Army, police and most civil servants were fired (termed de-Baathification) by Paul Bremer May 23rd, 2003 bringing chaos to the country over night. This event was the birth of the bloody insurgency that followed when disgruntled Iraqis began attacking coalition forces.
Some of what I learned:
- Desert storm was the first war of the big five: the Patriot missile system, the M270 MLRS (multiple launch rocket system), the M1 Abrams tank, the AH-64A Apache attack helicopter and the M2 Bradley fighting vehicle.
- Wars rarely turn out as envisioned by the ones who start them.
- The guerrilla wins by not losing.
- The word guerrilla is derived from the Spanish word Guerra for “war”.
- In 2003 the population of Baghdad alone was over six million. No wonder the military had issues establishing law and order.

This audio book is about twenty hours in duration. It took me two and a half days to finish. By far one of my favorite books on the subject of terrorism investigations and the attacks on the World Trade Center. This book is replete with info on the build-up to the attacks of that fateful Tuesday morning and the origin of al-Qaeda. It’s edge of your seat entertaining, well written and overtly insightful.
Ali H. Soufan is a Lebanese born former FBI special agent that is fluent in Arabic. He was the lead investigator into the 2000 USS Cole attack. He is mentioned in the 9/11 Commission Report (refereed to as Al S). He successfully interviewed some very high value targets (HVT’s) such as Abu Zubaydah and Abu Jindal. He discusses their interrogation and confessions in great detail. These interrogations lead to the identification and arrest of Khalid Sheikh Muhammed (KSM), the mastermind of 9/11. He retired from the FBI in 2005 and is CEO of The Soufan Group.
KSM on the night of his arrest. Doesn’t look very happy!
He makes it clear he was opposed to the EIT’s (enhanced interrogation techniques a.k.a. sleep deprivation and waterboarding) of detainees that the CIA insisted would break even hard-core fanatics. He is more than critical of the CIA and their mishandling of valuable information regarding the growing and serious threat of Bin Laden. He insists if there was more cooperation between governmental agencies at a minimum two of the nineteen hijackers would not have been allowed into the US and the attacks could have been prevented all together. (I have heard this from a few different sources). We cannot blame anyone for the attacks on the WTC other than bin Laden and al-Qaeda.
I loved his cogent and pragmatic interrogation style especially being a fellow Muslim; he gets right into their head with offerings of tea and politics. He seemingly makes them feel a bit of guilt for their crimes against innocents and fellow Muslims.
Some of what I learned:
- Talib (of Taliban) is Arabic for “student” or “one who seeks knowledge”.
- The US government uses the Barney song (purple dinosaur) on a loop to deprive detainees of sleep.
- Ali H. Soufan worked with special agent John P. O’Neill. Look him up.
- Before 9/11 the FBI had all of eight agents that were fluent in Arabic.

I have so much to say about this topic so I’ll keep it short. This audio book is almost eleven hours in duration and it took me two days to finish. I could have concluded it more quickly but I had to take a fair amount of notes, pause and rewind a few parts so I could decipher important material. This is a normal habit of mine; some books more than others.
Sean Carroll is a theoretical physicist at Caltech: in this book he describes the formation and discovery of the standard model of particle physics in easy to understand terms, the formation and cost of the LHC (Large Hadron Collider) and how this particle accelerator works. But the focus of the book is on the discovery of the higgs boson in 2012. Made possible by the collaboration of scientists from all over the world working at CERN (European Organization of Nuclear Research) in Geneva, Switzerland. This discovery was made by two independent teams: Atlas and CMS. The Higgs has a mass-energy of 125 GeV, no spin and exists in the lab for about a zeptosecond.
This is my personal favorite author on physics and I highly recommend this book. A superb intro into particle physics, this particular book was my first serious endeavor into elementary particles and I’ve been hooked ever since. I find his books easy to follow, easy to find, entertaining and scientifically stimulating. It’s quite fascinating that particles (including associated antimatter) have actually been observed and quantified in the lab with the exception of gravitons. I really enjoyed learning about the LHC and other particle accelerators in detail. These produce incredible amounts of data that need to be analyzed in detail and only a small fraction of this data is used.
The higgs boson is not your typical boson. The gauge bosons are the force carriers (photons, gluons, W and Z bosons). The Higgs is in a class all by itself (scalar boson). Think of the higgs as more of a field than a particle. This field is unique because it has uniform spatial density. All that means is the higgs has the same value everywhere in space. As opposed to gravity or electromagnetism where the force exerted obeys the inverse square law. Whether a million light years away or here on Earth the field is uniform. Named after Peter Higgs this elementary particle gives mass to subatomic particles via interactions with the higgs field. The higgs field has no effect on mass less particles (photons) and without said field all matter would travel at light speed. We wouldn’t even have the force of gravity. Aren’t audio books magical.
Peter Higgs (Nobel Laureate 2013 in physics)
Some of what I learned:
- Mass is a form of energy. At high enough temperatures mass and energy are interchangeable. Matter is energy at rest.
- 95% of the universe is made of dark energy/matter.
- When an electron and positron (antimatter) annihilate they give off a pair of gamma rays, which is used in medical devices.
- The internet was invented by CERN.
- The LHC is powered by electromagnets that need to be kept at 1.9 degrees kelvin, which is colder than space!
This audio book was eight and a half hours in duration and took me a day. I really enjoyed this book and couldn’t help but take it to heart. I was in Iraq during the invasion in 2003 and ended up getting stationed in Mosul with the 101st Airborne Division. I had the same MOS ( military occupational specialty) as she did: food service specialist (92G). The author is the first and only black female in the history of the US to be taken prisoner of war. She was part of six soldiers to be taken prisoner, including Jessica Lynch. They were in the enemy hands for three weeks until being rescued by US Marines.
This book gives an intimate and personal account of the 507th Maintenance Company being ambushed in Nasiriya March 23, 2003 shortly after the invasion of Iraq began. Their convoy missed a turn, ended up getting lost and had to turn around in a bad part of town. They were attacked by Fedayeen paramilitary forces and Iraqi military in civilian clothes using RPG’s, mortars and small arms. They fought for as long as they could but ended up surrendering to their attackers due to weapons malfunctions among other issues.
The 507th was a maintenance company that works on Patriot missile systems at Ft. Bliss (note: they were disbanded). The 507th lost eleven soldiers in the attack. My mobilization site was also Ft. Bliss and I remember going through CIF ( central issue facility ) at the end of my deployment and seeing their pictures on the wall in memorial. I will never forget seeing that. I was with the 137th Quartermaster Company and we lost one soldier on our deployment to hostile fire. That was a big deal; I can’t imagine losing eleven.
Some of what I learned:
- There are no safe jobs in the military.
- Her captures did not search her. She had sensitive documents in her pocket that she flushed down a toilet at first opportunity.
- Lori Piestewa was the first female native-american born US citizen to die in combat and her nick name was “pie”. Note: everyone in the military has (or is given) a nick name by their buddies.
- March 23, 2003 was the deadliest day of the war for US forces due to this attack and a friendly fire incident involving aircraft and US Marines.

I like it when audio books are read by the author. This is one of those. Maybe one in eight are read by the author and he did a stellar job. This book was captivating and totally sucked me in. The author seems like a pretty funny guy. I wouldn’t mind buying him a beer.
This book was nine hours in length and took me a day. It was an especially good book. He talks about: growing up in Montana, his decisions to join the military, Navy Seal training, something like four-hundred combat missions, his burning desire to avenge the WTC victims, killing the worlds most wanted terrorist and his reasons for not re-enlisting. He explains the formation of the Seal Teams and he even raised my low opinion of Richard Marcinko. One kinda sad thing about the book: the author was good friends with Neil Roberts. That was hard to hear.
He’s a talented writer: he is engaging, entertaining and hilarious. You know it’s a good audio book when you laugh out loud to yourself. I enjoyed the ending: He meets with some of the 9/11 families. Enough said.
I have read a fair number of books on the Bin Laden raid and it never gets old. This is one of the more intimate books on the subject. I’ve noticed that the higher ranking someone is in al-Qaeda, ISIS, or the Third Reich (for that matter) the more of a coward they are. Bin Laden didn’t have the brains to surrender nor the courage to go down fighting.
note: some parts are redacted by the DoD. Actually the only part that is redacted is the beep in Seal Team beep.
Some of what I learned:
- Cairo (the Belgian Malinois used in the Bin Laden raid) had previously been shot twice by some asshole hiding in a tree with an AK-47.
- No matter how many times I read about hell week during BUDs training, it always seems like hell.
- All stress is self-induced.
- Senior Chief Special Warfare Operator Edward C. Byers Jr. was the first Seal Team beep operator to win the Medal of Honor.

My current book is forty-five plus hours so it will take me at least three or four days total. Technically this would be my longest book ever. The Outline of History by HG Wells was forty-four hours followed by The Rise and Fall of the Third Reich by William L. Shirer at forty-one hours.
So we can talk about a book I finished recently. Big History: From the Big Bang to the Present by Cynthia Stokes Brown. This was eleven hours and took less than two days. I was surprised at how detailed this book was, especially regarding the big bang. It’s a great read.
What I learned:
- Matter and energy are interchangeable but only at temperatures approaching a trillion degrees. (E=mc²). So matter is energy at rest when not at those ungodly temperatures.
- The inverse square law gives rise to the elliptical movement of the planets. This was calculated by Sir Issac Newton and published in his paper Mathematical Principles of Natural Philosophy in 1687.
- The Club of Rome commissioned an article entitled The Limits of Growth in 1972. This was a computer simulation of exponential economic and population growth.
