Absolute Truth. An important issue in the philosophy of science is whether science deals with absolute truth. We can think about this issue by imagining the science of other civilizations. For example, would aliens necessarily discover the same laws of physics that we have discovered, or would the laws they observe depend on the type of culture they have? How does the answer to this question relate to the idea of absolute truth in science? Overall, do you believe that science is concerned with absolute truth? Defend your opinion.

- Why write numbers in scientific notation Understanding physics will help you describe in great detail how the world works. However, the characteristics of the world span an enormous range of numbers. The mass of an electron is 0.000000000000000000000000000000911 kg (incredibly tiny!). The mass of the Sun is 1,989,000,000,000,000,000,000,000,000,000 kg (incredibly massive!). If you had to write, interpret, or use these numbers as written, you could very easily end up making a minor math error. Scientific notation was invented to easily express numbers that are too large or too small to be conveniently written in decimal form. The advantages of scientific notation are it 1) is compact, 2) helps articulate significant figures, and 3) works with numbers of any size. The traditional format for numbers written in scientific notation is m × 10 n is where m is a number between 1 and 10 and n is an integer (either positive or negative). For the examples above, the mass of an…arrow_forwardplease help me with this problem. ASAP! show complete and explicit solution. do not skip any mathematical steparrow_forward7arrow_forward
- An isotope of a radioactive element has half-life equal to 9 thousand years. Imagine a sample that is so old that most of its radioactive atoms have decayed, leaving just 25 percent of the initial quantity of the isotope remaining. How old is the sample? Give your answer in thousands of years, correct to one decimal place.arrow_forwardI'm pretty sure I got the first step right, but I'm really struggling with the second step. I think I set up the equation correctly, but when it comes to actually solving, I'm not getting the steps right. Can you please list out step by step how to solve the equation in part 2, assuming I got that equation right. I've attached the problem, as well as my work.arrow_forwardWhen asked about his thoughts on a new scientific hypothesis, Wolfgang Pauli once said: “That's not right, that's not even wrong.” What fundamental principle of science was he alluding to? And why is the second part of this quote more important than the first?arrow_forward
- Oxygen Atoms in People. Figure 5.7 shows that oxygen makes up about 65% of the mass of a human being. A single oxygen atom has a mass of 2.66 × 10−26 kg. (a) Use this fact to estimate the number of oxygen atoms in your body. (Hint: If you know your weight in pounds, you can convert to kilograms by dividing by 2.2.) (b) Compare your answer to the number of stars in the observable universe (which is roughly 1022).arrow_forwardHello Sir! Please solve question numbers 1 and 2.
