The twentieth century has made several revolutions such as today's web, cloning, theory of relativity, transistor, laser, biotechnology and computer.
The basis for all those revolutions lies in the knowledge about atoms, cells and computers, their fast developments. In future, they will combine and do wonders in the middle of the 21st century.
That is biotechnology and computers will do wonders in future combined with quantum principle, all impossible today can become possible tomorrow. As per today's estimation humans' knowledge is doubled every 10 years, computer power every 18 months and DNA sequencing in 2 years. If this condition is continued, we cannot foresee how would be middle of the 21st century.
Depending upon human knowledge and developments computer power has also improved unexpectedly. Since the invention of the first computing machine by Jack Kilby in the year 1958 at Texas University, it has been reducing in size, and now attained in nanolevel devices as shown in figure 1. It is a wonder to know how the size is decreased while increasing density of the data. The only answer is nanotechnology, atom or molecular level devices with high-density memory, and molecular machines still can make wonders in future.
Computer generations
The basic element of a computer, the integrated circuits (ICs) made from tiny electronic components such as resistor, inductor and capacitor are functioning as heart and brain of a computer. Lots of changes are produced on the parts and size of the elements. Based on the changes and related improvements the computer improvements are classified as 5 generations. Lee.

Building world's 1st pyramid
In a preprint study published this summer, researchers proposed that ancient Egyptians built the world's first pyramid the 4,700-year-old Step Pyramid of Djoser, which sits on Egypt's Saqqara plateau using a \"modern hydraulic system\" powered by a long-gone branch of the Nile River.
Climate change arms the world, ovarian cancer pulls the trigger.It's time we disarm them both
Climate change, driven by human activities, leads to environmental changes such as rising temperatures, altered weather patterns, and increased pollution.
Climate Change Added 18 mph to Hurricane Wind Speeds over Past 5 Years
High ocean temperatures caused by global warming boosted maximum intensities for most storms between 2019 and 2023, as well as for every 2024 hurricane.
How Indian Vulture Decline Led to 500,000 Deaths in 5 Years
Once a common sight across India, vultures were abundant scavengers, often seen circling landfills in search of carcasses.
Understanding Monkeypox: Insights and Implications
Monkeypox, a viral zoonotic disease, has gained significant attention in recent years due to its re-emergence and sporadic outbreaks globally.
AI predicts that most of the world will see temperatures rise to 3°C much faster than previously expected
Three leading climate scientists have combined insights from 10 global climate models and, with the help of artificial intelligence (AI), conclude that regional warming thresholds are likely to be reached faster than previously estimated.
Infrared Radiation: A New Player In Mosquito Host-Seeking
The sound of mosquitoes is all around us when the sun sets and the air gets warm and sweltering.
Fish Oil May Benefit to Cure Alzheimer's, disorder: new findings
The benefits of fish and fish oil consumption are well-known in medical science as fish is considered a precious food resource that provides sufficient nutrition to humans.
A new class of antivirals could help prevent future pandemics
The arrival of Paxlovid in December 2021 marked another turning point in the COVID-19 pandemic an effective antiviral that has since successfully treated millions.
Turning carbon emissions into methane fuel
Chemists have developed a novel way to capture and convert carbon dioxide into methane, suggesting that future gas emissions could be converted into an alternative fuel using electricity from renewable sources. Carbon dioxide (CO2) is a greenhouse gas that accounts for a large part of Earth's warming climate, and is produced by power plants, factories and various forms of transportation.
