Alexei Starobinsky 1970-01-01
Alexei Starobinsky is a prominent Russian theoretical physicist renowned for his contributions to cosmology and quantum field theory. He is particularly well known for his work on the early universe, including the concept of cosmic inflation. In the early 1980s, Starobinsky proposed a model of inflation that describes the rapid expansion of the universe just after the Big Bang, which helps to explain the large-scale structure of the cosmos as well as the uniformity of the cosmic microwave background radiation.
Black-box obfuscation 1970-01-01
Black-box obfuscation is a technique in computer science and cryptography that aims to make a program or algorithm difficult to understand or reverse-engineer while still preserving its original functionality. The goal is to ensure that an adversary, given access to the obfuscated program (or "black box"), cannot efficiently glean any useful information about its internal structure, logic, or sensitive data, apart from its inputs and outputs.

1-K pot 1970-01-01
A 1-K pot, or a 1 kΩ potentiometer, is a variable resistor with a resistance value of 1 kilo-ohm (1,000 ohms). Potentiometers are commonly used in electronic circuits to adjust levels of voltage, resistance, or signal strength. They typically have three terminals: two outer terminals connected to a voltage source and one wiper (middle terminal) that moves across a resistive track to adjust the output voltage or resistance.
29th meridian east 1970-01-01
The 29th meridian east is a line of longitude located 29 degrees east of the Prime Meridian, which runs through Greenwich, England. It is a vertical line that extends from the North Pole to the South Pole, passing through several countries in Europe and Africa, including parts of Norway, Sweden, Denmark, Germany, Poland, Ukraine, Romania, and countries in northeastern Africa such as Egypt and Sudan.

HMS Vanguard and Le Triomphant submarine collision 1970-01-01
The collision between HMS Vanguard and Le Triomphant refers to an incident that occurred in February 2009 involving two nuclear-powered submarines: the British HMS Vanguard and the French Le Triomphant. HMS Vanguard is a British Royal Navy submarine and one of the four submarines of the Vanguard class, which serves as the UK's nuclear deterrent. Le Triomphant, on the other hand, is a French Navy submarine of the Triomphant class, also designed for strategic deterrence.
Warm-blooded 1970-01-01
Warm-blooded, or endothermic, refers to a characteristic of certain animals that can maintain a relatively constant body temperature regardless of the external environment. This ability allows warm-blooded animals to remain active and functional in a variety of climates and conditions, as they can generate and regulate their body heat through metabolic processes.

Eugenie Lisitzin 1970-01-01
Eugenie Lisitzin is often associated with the field of oceanography, particularly known for her work on the interaction between the ocean and the atmosphere, as well as ocean wave phenomena. He is a prominent figure in the study of wave dynamics and has contributed to the understanding of oceanic processes related to waves and their impact on marine environments.
Indian crystallographers 1970-01-01
Indian crystallographers are scientists and researchers from India who specialize in the field of crystallography, which is the study of crystals, their structures, and the arrangement of atoms within them. Crystallography is essential in various scientific disciplines, including chemistry, physics, and materials science, and plays a crucial role in understanding the properties of materials, drug design, and the development of new technologies.
Reaction rate 1970-01-01
Reaction rate refers to the speed at which a chemical reaction occurs. It is typically defined as the change in concentration of a reactant or product per unit of time. This can be expressed in various ways, such as: - **For reactants**: Decrease in concentration = -Δ[A]/Δt, where [A] is the concentration of the reactant.
2000s United States housing bubble 1970-01-01
The 2000s United States housing bubble was a significant period of rapid increase in housing prices across the United States from the late 1990s until around 2006. This phenomenon was characterized by a combination of factors that led to an unsustainable surge in real estate prices, ultimately culminating in a sharp decline and the 2008 financial crisis.
The United States Invitational Young Physicists Tournament (USIYPT) is an annual competition that encourages high school students to engage with physics concepts through collaborative problem-solving and written reports. Modeled after similar tournaments in other countries, the USIYPT provides students with the opportunity to explore advanced topics in physics by working in teams to study and present specific physics-related problems or projects. Participants typically form small teams, conduct research and experiments, and prepare presentations on their findings.
