Advances in Technology Post WW2
Transcript of Advances in Technology Post WW2
Around the WW2 era, computers started to become more advanced and more useful throughout the war.
Colossus and the Bomba were computers used to decipher codes of high- level German army messages, otherwise known as the Cryptanalysis of the Lorenz cipher. Bomba Enigma codes, Colossus Fish codes; both codes used my allied forces.
Harvard Mark I used by the US Navy for many general purposes. Also used to solve a difficult system of partial differential equations for Los Alamos. The Los Alamos was an improvised computer used to model nuclear bomb designs.
Many analog mechanical computers were used for various purposes.
Submarine torpedo targeting computer sytems, Autopilot and RADAR antiaircraft computers etc.
Computers have a major impact on daily living because computer technology is nearly used in every area of our lives.
Banking and finance, manufacturing, medical field, transportation, entertainment, communication, military use, government, appliances, education, science and research.
As time and technology have progressed, computer technology, for the most part is becoming smaller and more portable.
Desktops -> Laptops -> Tablets -> Smartphones ->
At the beginning of the 21st century, statistics show, it was estimated there were about six computers for
every ten people in the United States. Electronics during WW2 rose to prominence very quickly. Prior to the war, some electronic devices were seen as important pieces of equipment. War instruments like radar systems and ASDIC (sonar) technology had proven their value during the war.
Additionally, equipment designed for communications and the interception for those communications were becoming very important.
After the war, the technology in communications were becoming more advanced at a rapid pace. For example, phones and radios, became a world wide communication.. This allowed different nations of power to negotiate with each other before blowing each other up. TV is another form of communication... Visual messages increased propaganda, advertisements were more wanting.
Created in the 1960s, the Internet was originally designed for military use... A way for government researchers to store and share information. It was not until January 1, 1983, hence the birth of the Internet, where the internet was improved to where computers could communicate with each other and network servers were created to store, share and search information for all crowds.
A satellite is a body that orbits another body. For example, Planet Earth is a satellite to the sun because it orbits the fire ball. Our Moon orbits Earth which makes the Moon a satellite. Artificial Satellites and Natural Satellites. The first Artificial Satellite was the Sputnik 1 designed by the Russians
Satellites have a birds-eye-view of Earth which means satellites can see large areas of Earth at one time. This ability means satellites can collect more data, more quickly, than instruments on the ground.
Satellites do much scientific work for scientists, astronomers, meteorologists, etc. Satellites can see much better into space than telescopes on surface. Flying above clouds and avoiding dust particles allow satellites a better view into space. Take pictures of Earth to help meteorologists predict the Weather.
Satellites helped communications become more efficient, fluid and advanced. When sending emails, texts, phone calls or other types of communications... Conversation through technology became more fluid. Es3- How did the advancements in medicine improve human conditions post WW2? Es2- How did communications change after the second half of the 20th century. During the second World War, there were many changes in medicine that continued on after the war.
Newer drugs and devices including better understanding of disease mechanisms have greatly improved the care of patients.
National Health Service (NHS) a publicly funded health care system in the UK that provides free medical care for all regardless of wealth.
Improvements in pregnancy and childbirth included the ability to induce labour and the use of epidurals to ease difficult pregnancies.
Vaccines were developed to control childhood diseases. Because of vaccines against polio, measles, rubella and other childhood diseases, the health of children was generally better than at any other time in history.
The discovery of DNA by Wilkins, Crick and Watson with the help from Rosalind Franklin helped researchers identify specific genes that are responsible for specific diseases.
The ultrasound and magnetic resonance made it easier to diagnose disease. Professor Ian Donald, of Midwifery at Glasgow developed ultrasound in the 1950’s for looking at unborn babies. Magnetic Resonance Imaging (MRI) can be used to detect diseases without the use of radiation making it less harmful to the patient.
Advancements in surgery has changed drastically since WW2; equipment, tools, etc
New drugs are being used for a variety of physical and mental illnesses, allowing improved quality of life.
Advancements in diagnoses and treatment allowed people to live longer than ever; United States life expectancy in the second half of the 20th century was about 58 years, while in 21st century, it was almost 77 years and above. Es4- What advancements were made in Weapon technology due to the Cold War? After the second world war, a rivalry began between the United States and the Soviet Union called the Cold War... The Cold War was described by a fight between democracy and communism with a constant threat of nuclear war from apposing countries.
The major feature of the Cold War was the arms race between the member states of the Warsaw Pact and those of NATO. This resulted in substantial scientific discoveries in many technological and military fields.
The technological and military advancements particularly focused on revolutionary advancements in the field of nuclear weapons and rocketry, which later led to the space race; many of the rockets used to launch humans and satellites into orbit were originally based on military designs formulated during the Cold War.
Fields in flight technology and hardcore missiles were also included in the arms race: jet fighters, bombers, chemical weapons, biological weapons, anti-aircraft warfare, surface-to-surface missiles (including SRBMs and cruise missiles), inter-continental ballistic missiles (as well as IRBMs), anti-ballistic missiles and anti-tank weapons.
Water warfare and reconnaissance was very big in addition to the arms race: Submarines and anti-submarine warfare, submarine-launched ballistic missiles, electronic intelligence, signals intelligence, reconnaissance aircraft and spy satellites.
In a nutshell advancements during the Cold War included nuclear, biological, and chemical weapons along with new delivery systems. Es5- What are the top technological advancements of the decade and how does it affect society? As humans We've come a long way in just 10 years. From various of technologies such as the Internet, computers, and electronics, it has steadily evolved into the lives of mainstream America.
We've witness the birth of social networking, the slow death of wires, and the growth of both entertainment and business technology to the point that the gadgets, computers, and instruments we use today in both work and play look far different from those we used back in 2000.
These 10 technological advancements represent the biggest and most influential changes we've seen in consumer electronics in the last decade.
In this category of technology TVs including HDTVs has become more detailed than ever.When detail went up, size has gone down; in just 10 years, televisions has transformed from huge blocks into sleek, flat surfaces. What was once a massive box filled with glass, tubes, and other products, TVs have become an inch-thick panel where you could hang on your wall.
DVRs allow the user to record their favorite TV shows or movies and watch them for later. TiVo popularized the DVR, but now a days every major cable and satellite provider offers some form of digital video recorder. No more fumbling with cassette tapes or struggling with tiny buttons and small unhelpful LED displays on the top of VCRs. You just simply select and record what you want. Missing out on your favorite TV shows is now a thing of the past.
Internet during the 90s worked but wasn't pleasant. The internet today is always available and blazing-fast for us to upload, download, communicate, and simply function online at speeds several factors.
Households, cafes, bookstores and others in relation all have Wi-Fi hotspots. Wi-Fi is extremely useful for hopping online instantly from any electronic device and surfing the internet or do your likings.
Our cell phones aren't just phones anymore. They're portable computers and are probably the most thing we pay attention to. With the advent of the iPhone, Blackberries, and Android-powered devices, what were once humble handheld telephones are now all-in-one tools for work and play.
Bluetooth is an open wireless technology standard for exchanging data over short distances (using short wavelength radio transmissions).
Online Media Services
From the VHS tapes and the DVDs then to Blue-ray DVDs, online media services allow the user to watch their favorite TV shows, movies, or stream music right on their computer; Netflix, Hulu, YouTube
Online Gaming Services
