An Introduction to the History of Science
An Introduction to the History of Science
by W.Libby
Edition: Hardcover

1.0 out of 5 stars Blatant Bias, 24 Mar 2014
Verified Purchase(What is this?)
This is the most biased book I have ever read, apart from the political propaganda of undemocratic states.
This is an example
It gives a full chapter (13 pages) on the invention of the aeroplane by Samuel Pierpont Langley crediting him with its invention and first flight.
It mentions Bleriot as the aviator whose plane confirmed Langley's achievement.
The Wright brothers are not mentioned at all except in a footnote which simply mentions that they won a Langley Award, without ever mentioning that they made or flew a plane. Their names do not even appear in the index.
Shocking

1.0 out of 5 stars A nightmare, 2 Jan 2014
Verified Purchase(What is this?)
I have been using PCs and PC applications software since the Apple II was launched in the UK in 1978 and the documentation and software provided with the Samsung SE 506BB machine were unquestionably the worst I have ever had the misfortune to use in those intervening 36 years.

The installation instructions tell you <<< only >>> the how to plug in the single USB cable which comes with the drive into the USB socket in your computer or TV and into the drive. Nothing could be more obvious!!! That's it. Nothing about getting it to work.

The software is another matter. It's certainly not plug and play. You have to install the Cyberlink software yourself and it doesn't work without a patch but this is not pointed out anywhere in the documentation. The patch is not included on the disc provided with the drive and you have to download the patch (They confusingly call it an "Upgrade") from Cyberlink, the software provider.
Error messages kept cropping up throughout the installation process but there was no explanation as to the cause nor to the cure. The help screen was completely useless and did not cover these messages.
Worse still, twice during installation, the software requested a restart and both times it inexplicably disabled both the keyboard and the mouse and hung the computer with a blank screen for a nail-biting 30 minutes before it came back to life. It would not even let you turn it off.

Even after it is installed, the operating software left much to be desired. It was unclear as to the different processes required to write videos or copy files and the on-screen controls were not explained and non intuitive.
Blu Ray playback performance was difficult to start and jerky when it did.
I got help from various user groups who were equally critical of the lack of support by Samsung and Cyberlink for the product. Writing Blu Ray discs and compatibility with Apple software seem to have been the main problems highlighted in the user groups. (My operating system is Windows 7)

My conclusions:
It's cheap. It works. (It writes DVDs but I have not yet attempted writing a Blu Ray disc.) But it's a struggle.

1.0 out of 5 stars Unbelievable errors. How can it be taken seriously?, 2 Sep 2013
Verified Purchase(What is this?)
One of the headline performance attributes of the V-2 was its speed.
On the two occasions where this is mentioned it is incorrect by a factor of 10 !!!
Such obvious gross errors in such an important fact.
How can you believe anything else this author has to say?

1.0 out of 5 stars Not what it says on the cover, 2 Feb 2013
This book is "remaindered" in the UK and well it should be.
It claims to be "the definitive reference" and covers "significant events".
It does not have any specific entries for any of the pioneering aircraft types such as Boeing 747 or the Concord. (It has entries about companies).
If you want to know who designed a particular aircraft, or anything about it - Tough luck.
There are no entries for technologies such as "supersonic flight" or "ejector seats" or "navigation"
There's no reference for "passenger aircraft" or "passenger jets"
The section on "jets" is less than one page long.
The section on the "Battle of Leyte Gulf" is more than two pages long.
The aviation timeline has no entries betweem 1976 and 2000!!!
I could go on.
Don't buy it.

5.0 out of 5 stars What an Amazing Book!!, 26 Jan 2013
Verified Purchase(What is this?)
Its coverage is both broad and deep.
Simonyi provides a completely new format for presenting science history bringing together the science at a fundamental level (not just "popular science"), the biography and thoughts of the scientist, the context of the science and its relationships with other developments.
One of the best books in my library.

2.0 out of 5 stars It can't be serious, 10 Sep 2012
Verified Purchase(What is this?)
This review is from: Engineers (Hardcover)
The Introduction does say that it focuses on great schemes attributed to single individuals. Nevertheless there are serious omissions.
NOTHING on steam turbines which are responsible for generating 80% of the world's electricity.
NOTHING on nuclear power.
NOTHING on the two pioneers who first transmitted sound on radio waves (Fessenden for AM and Armstrong for FM).
NOTHING on the pioneers of TV transmission.
NOTHING on electronics and semiconductors - Not even a mention of the transistor or the integrated circuit.
NOTHING on computers. (Sorry - One short paragraph in a book of 360 pages)
NOTHING on software
NOTHING on the internet or the World Wide Web.
NOTHING on mobile phones.
NOTHING on chemical engineers, chemicals, materials, plastics and metals except for a section about Bessemer.
It's hard to believe but I could go on.
I won't mention the errors, others may have taken this up.
Though the Large Hardon Collider gets a couple of pages, there's not a mention of a single name of anyone associated with the project.
Surely there were stand-out engineers responsible for these developments and advances (or "advancements" as they are called in the book)
How can this be a serious book about engineers?

1.0 out of 5 stars This book is rubbish. Don't buy it., 10 Sep 2010
Verified Purchase(What is this?)
I bought this book expecting it to contain some useful information and facts.
It contains 87 pages of quizes, tests and exams and 16 blank pages.
Not much room for facts!
The meagre information it does contain is useless and misleading.
Examples:
1)"Nano materials used for battery separator plates hold much more energy than conventional batteries" But battery separators are inert and do not store energy. Energy is stored in the active chemicals!
2) "Batteries made of nanocrystalline nickel will hardly ever need charging" Maybe the authors have found the secret to perpetual motion.
Even the very basic fundamental definitions are wrong.
Example: "Hertz - The frequency at which alternating current changes direction." (It actually changes direction twice per cycle)
Much of the text is off topic.
Example: It has a whole chapter about energy which includes only one minor reference to nanotechnology speculating that making transmission cables from nanotubes could reduce transmission losses and power outages.
I could go on.....
How can you take this book seriously?
Don't buy it. It could get you into trouble if you depend on it for answers.


John R. Pierce: Pioneer in Satellite Communication (Unlocking the Secrets of Science)
John R. Pierce: Pioneer in Satellite Communication (Unlocking the Secrets of Science)
by Jim Whiting
Edition: Library Binding

1.0 out of 5 stars A complete lack of substance, written by somebody who knows little about the subject, 3 Jun 2010
Only 45 pages long, with large type. Its treatment of the subject is very superficial.
It makes no mention of what Pierce's contributions to satellite communications actually were.
It mentions his patents without saying what they were.
It mentions Telstar without describing its contents or performance.
A completely worthless book with an exorbitant price. Don't buy it.
