Science, Mathematics & Technology Quiz

August Ferdinand Mobius was a 19th-century German mathematician and astronomer who made significant contributions to geometry and number theory. The Mobius strip is a non-orientable surface with only one side and one boundary, created by twisting a strip of paper 180 degrees and connecting the ends.

Robert Jemison Van de Graaff invented the Van de Graaff generator in 1929, an electrostatic generator that can produce high voltages used in particle accelerators. While mostly replaced by more powerful devices, it remains popular for educational demonstrations because it safely shows static electricity principles.

Hans Geiger worked with Ernest Rutherford on radioactivity experiments and developed the Geiger counter in 1908, a device that detects and measures ionizing radiation. He also co-developed the Geiger-Marsden experiment (gold foil experiment) which led to the discovery of the atomic nucleus.

Hermann Rorschach developed the Rorschach inkblot test in 1921, a psychological test used to analyze personality and emotional functioning through interpretation of symmetric inkblot images. His childhood nickname 'Klex' (German for inkblot) foreshadowed his most famous contribution to psychology.

Erwin Schrodinger developed the wave equation in 1926, a fundamental equation in quantum mechanics that describes how the quantum state of a physical system changes over time. His famous thought experiment, 'Schrodinger's cat,' illustrates the paradox of quantum superposition - the cat being simultaneously alive and dead until observed.

ENIAC (Electronic Numerical Integrator and Computer) was the first general-purpose electronic digital computer, completed in 1945 and formally dedicated in February 1946 at the University of Pennsylvania. Harvard Mark I was electromechanical, not fully electronic.

ENIAC is widely regarded as the first electronic general-purpose computer. The question is somewhat ambiguously worded - 'first computer' could mean different things, but ENIAC was the first all-electronic digital computer, unlike earlier electromechanical devices.

The Intel Pentium processor was introduced in 1993, succeeding the 486 processor line. It was a significant advancement in x86 architecture and became very popular in personal computers.

ENIAC was developed from 1943-1946 at the University of Pennsylvania in the USA and was formally dedicated in February 1946. This makes '1946 in U.S.A.' the correct answer.

Charles Babbage designed the Difference Engine and Analytical Engine in the 19th century, establishing fundamental principles of modern computing including programmability and the concept of a general-purpose computer.

A modem (modulator-demodulator) converts digital signals (bits and bytes) into analog signals for transmission over telephone lines and performs the reverse conversion when receiving. Sensors detect physical quantities, and transistors are electronic components.

Ted Nelson wrote 'Computer Lib/Dream Machines' in 1974, which was one of the first books about personal computing and hypertext. George Boole developed Boolean algebra, and John Napier invented logarithms. Option C 'Miami, Florida' is clearly a distractor.

Assuming the Encyclopedia Britannica is roughly 1-2 GB, at 2 Gbps it would transfer in approximately 0.5-1 second. However, this question requires specific assumptions about encyclopedia size and transmission rates that aren't provided.

Niklaus Wirth developed Pascal in the late 1960s/early 1970s. It was named after mathematician Blaise Pascal and designed to teach structured programming. COBOL was developed by Grace Hopper's team, and FORTRAN by IBM.

Sir Alexander Fleming discovered penicillin in 1928 at St. Mary's Hospital, London, when he noticed mold killing bacteria in a petri dish. This accidental revolution in medicine earned him the Nobel Prize. Sir Almroth Wright worked on vaccines, Hopkins discovered vitamins, and Neuberger was a biochemist - none discovered penicillin.

In influenza viruses like H1N1, the H refers to hemagglutinin, a surface glycoprotein that helps the virus bind to host cells. The N refers to neuraminidase. Haemoglobin carries oxygen in blood (not viral). Hongkong is a place. Hemoprotein is a general term for iron-containing proteins, not the specific viral protein.

In H1N1 influenza virus, the 'H' stands for hemagglutinin, which is a surface glycoprotein that helps the virus bind to and enter host cells. The 'N' stands for neuraminidase.

Sir Alexander Fleming discovered penicillin in 1928 at St. Mary's Hospital in London when he noticed that mold (Penicillium notatum) had antibacterial properties against staphylococci.
