Throughout their millennia-old history, these People, working diligently and creatively and fighting courageously to build and defend their country, have forged a tradition of patriotism, solidarity, humanity, justice, resilience and indomitableness, and have created their civilization and culture.
Who are Vietnamese? (According to the Vietnamese constitution)
In computer logic and mathematics, this is a smaller, "helper" statement that is proven true first, so it can be used to solve a bigger, more complex problem.
What is a lemma?
In Roman numerals, putting a smaller value before a larger one means subtraction (e.g., IV=4). What modern number is represented by XL?
40
Modern CPUs contain billions of these microscopic semiconductor switches that turn electric current ON (1) or OFF (0) without any moving parts.
What is a Transistor?
Many strategy video games (like Civilization) use grid maps made of this regular polygon (internal angle = 120 degrees) instead of squares.
What is a Hexagon?
Messi wore his number 10 after this grinning Brazilian departed Barcelona—a two-time World Cup winner and 2005 Ballon d'Or recipient.
Who is Ronaldinho Gaucho?
AND operator outputs True only when both inputs are True; otherwise, it outputs False. An XOR operator outputs True only when exactly one input is True; if both inputs are the same, it outputs False.
Find:
(True AND False) XOR True = ?
True
If you count normally on your fingers, you can only reach 10. But if you treat each of your 10 fingers as a binary bit (1=finger up, 0=finger down), what is the maximum number you can count to using both hands?
1023
Ex: First student to show 6 7 on their two hands gets 2 Homework Free tickets.
Natural real-world data—like human voice, ambient temperature, or light intensity—is continuous and smooth. What term describes this non-digital physical signal?
What is an Analog signal?
A point in a 3D modeling program moves from position (1,2,3) to (1,5,7). How far has the point moved?
5 units
A system that represents letters and numbers using short and long signals, arranged in specific patterns that can be transmitted on and off over a channel (like a light, sound, or electrical signal).
What is Morse code?
This British mathematician cracked the German Enigma code in WWII, imagined a theoretical "machine" that defines what computers can compute, and was later persecuted for his sexuality — a famous ethical stain on scientific history.
Who is Alan Turing?
The ancient Babylonians used a Base-60 system. Name two everyday measurements we still use today that are based on this ancient 60-unit system!
What are Time (60 seconds/minutes) and Angles/Circles (360 degrees, 6×60)?
Satellite navigation systems (GPS) must constantly adjust their internal clocks because time runs slightly faster in space than on Earth due to weaker gravity. Name Albert Einstein’s famous theory that explains this phenomenon.
What is the Theory of Relativity (or General Relativity)?
This 3rd-century BCE Greek mathematician wrote Elements. His principles of flat geometry form the foundation for 2D graphics rendering engines today.
Who is Euclid?
A Vietnamese-American computer scientist and artificial intelligence researcher. He is a Google Fellow at Google DeepMind and a founding member of the Google Brain project.
Lê Viết Quốc.
You and an opponent play a game with a pile of 21 matchsticks.
On your turn, you can take 1, 2, or 3 matchsticks.
You take turns.
The player who is forced to take the very last matchstick loses.
You are allowed to go first. How can you guarantee a win?
You can not.
You are cracking a 3-digit vault code (ABC).
- The sum of the digits A+B+C=14.
- Digit C is exactly double digit A.
- Digit BB is an odd prime number (3,5,7…).
Find the correct 3-digit sequence ABC.
356
Microchip manufacturers are reaching the physical limits of miniaturization because transistors are now only a few atoms wide. Electrons can spooky-leap directly through solid physical barriers, causing leaks. What quantum physics phenomenon causes this barrier-jumping?
What is Quantum Tunneling?
An AI camera detects an object inside a rectangular bounding box defined by a top-left corner at (10,20) and a bottom-right corner at (50,50). What is the total area of this bounding box in pixels?
1,200 pixels
Every non-constant polynomial equation you can write down has a solution among these numbers — none escapes. To achieve that, the line had to widen into a plane: each of these is fixed by two coordinates, one measuring the familiar direction, the other a perpendicular direction generated by a quantity whose square is −1.
What are complex numbers?
