In summary, the conversation discusses a well-known mathematical puzzle involving determining the weight of a different ball among a set of twelve balls using a balance scale. The puzzle has a traditional origin and has been used in various contexts, including a computer game. The conversation also mentions the long-standing history of Chinese mathematics.

There are 12 balls, including a ball with other balls, it is lighter or heavier than others, can you use a Balance without weights to find out the different ball Up to three times?

Unfortunately, I'm not sure if this is really for "General Math," this is a pretty well-known puzzle, and relies on one's general cleverness as opposed to one's mathematical cleverness.

Probably a better translation would be (no offence):

"Suppose you have three balls, one of which is either lighter or heavier than the others. With a balance-based scale, is it possible to determine which ball is the one with a different weight, and whether it's heavier or lighter, in three balances?"

there are twelve balls,but one of them is different.
Different is its weight
 
  • #4
can you find the different one ?
Only one way

You have now posted 7 times in this one thread with only two responses. Yes, Chinese mathematics has a long and noble heritage. And determining which of a set of balls, or coins, weight more or less than the others is an old, traditional puzzle (it even appears in one of the old "Zork" computer games by Infocom). But what is your point?

1. Can you explain the concept of "finding different ball by three times"?

"Finding different ball by three times" refers to the process of repeatedly searching for a specific ball among a set of three identical balls. This is often used in games or experiments to test one's ability to identify small differences between objects.

2. Is it possible to find a different ball by three times?

Yes, it is possible to find a different ball by three times. However, it requires a keen eye and attention to detail, as the differences between the balls may be subtle.

3. What factors can affect one's ability to find a different ball by three times?

Some factors that can affect one's ability to find a different ball by three times include the size and color of the balls, the lighting in the environment, and the speed at which the balls are presented. Other factors, such as distractions and fatigue, can also play a role.

4. How can finding different ball by three times be used in scientific research?

Finding different ball by three times is often used in cognitive and perception studies to understand how the brain processes visual information and detects differences between objects. It can also be used in quality control measures, such as testing for consistency in manufacturing processes.

5. Are there any limitations to using finding different ball by three times as a method of testing visual perception?

While finding different ball by three times can be a useful tool in studying visual perception, it is important to note that it may not accurately reflect real-world scenarios. In everyday life, objects may have more noticeable differences and are not presented in a controlled environment. Additionally, individuals may have varying levels of visual acuity and attention, which can affect their ability to detect differences between objects.
