In summary, the conversation discusses the use of angular units and the definition of parsec and parallax by astronomers of Venus. It is noted that they use the same method as humans but measure in their own units. The conversation also mentions the venusial diurnal parallax of the Sun and the fact that citizens of Venus have two hands with 7 fingers each. The origin of the 360-degree system and the Sumerians is briefly mentioned.

Hello everyone!
I just was reading Your questions and was interested in IAO problems.
There are only problems without solutions of 2011 year in the net, but i found IAO 2005 problems. So i can not understand how to solve some of them.

Like humans, astronomers of venus use the same method for definitions of parallaxes and of parsec but measure them in different (their own) units. For example, the distance to Sirius equals to 19.6 vpc (venusial parsec).
-Describe the most evident system of angular units used by astronomers of venus.
-Calculate the venusial diurnal parallax of the Sun.
Citizens of venus have two hands as humans and 7 fingers at each hand.
Thank you for comments!

why on Earth (literally! :biggrin:) do we divide the circle into 360 degrees?

what on Earth is the definition of parsec and parallax? :wink:

Blame it on the Sumerians, base 60 was their idea. We still use it for time keeping and geometry. It is cleanly divisible by every integer from 1 to 10, except for 7 - which may explain ancient superstitions about the number 7.

What is magnitude and why is it important in science?

Magnitude is a measure of the size or intensity of a physical quantity. In science, it is important because it allows us to compare and quantify different phenomena, such as the strength of an earthquake or the brightness of a star.

How do you calculate magnitude?

The specific formula for calculating magnitude depends on the physical quantity being measured. For example, the magnitude of an earthquake is calculated using the Richter scale, which takes into account the amplitude of the seismic waves. In general, magnitude can be calculated by measuring the physical quantity and comparing it to a known standard or reference.

What is the difference between magnitude and magnitude scale?

Magnitude refers to the actual numerical value of a physical quantity, while magnitude scale is a system used to categorize or scale the magnitude of a phenomenon. For example, the Richter scale is a magnitude scale used to categorize earthquake magnitudes.

Can magnitude be negative?

Yes, magnitude can be negative. This is typically seen in physical quantities that can have both positive and negative values, such as velocity or charge.

How accurate are magnitude calculations?

The accuracy of magnitude calculations depends on the precision of the measurements and the formula used. In general, scientists strive to make accurate measurements and use reliable formulas to calculate magnitude.
