Use a search engine such as Google to find information about Gordon E. Moore and Moore’s law, the famous law about technological advances that he proposed.
(a) What is Moore’s law? Give a brief description in your own words.
(b) Who is Gordon E. Moore? What was his position at the time he first proposed Moore’s law? What company did he later cofound? With whom did he cofound this company?
(c) In what field did Gordon E. Moore obtain his BS degree? At what university did he receive his BS degree? Where did he obtain his PhD degree? In what field was his PhD degree?
(d) What Nobel Prize-winning physicist gave Gordon E. Moore his first job opportunity?
(e) What was the number of the first microprocessor developed at Moore’s company and how many transistors did it have! When was it introduced!
(f) Read the article by Thomas Friedman on Moore’s law, and watch the video of his interview of Gordon E. Moore.9 In what year in what publication did Moore make his prediction? What was the most important lesson that Moore learned from his law? What stimulated his interest in science and engineering? What does Moore see as the biggest problem in science? How would you describe thestatus of Moore’s Law today!
(g) One important benchmark ofcomputational progress is the performance-to-price ratio (PPR) of computers.10 The PPR is the number of bits per word divided by the product of cycle time (1/clockspeed) and price. The original IBM PC (1981) with an 8bit word length, a 4.77 MHz clock, and a pricetag of $5000 came in with a PPR of ~7600. Computers based on other processors available in 2000 are listed in the following table.10 Calculate the PPR of each of these computers. Does Moore’s law hold forthe PPR? How did you come to your conclusion?

Check out a sample textbook solution- Mixtures of gases are always true solutions. True or false? Explain why.arrow_forwardIn the 1986 Lake Nyos disaster (see the chapter introduction), an estimated 90 billion kilograms of CO2 was dissolved in the lake at the time. (a) What volume of gas is this at standard temperature and pressure? (b) Assuming that this dissolved gas was in equilibrium with the normal partial pressure of CO2 in the atmosphere (0.038%, or 0.29 torr), use the Henrys law constant for CO2 in water to estimate the volume of Lake Nyos.arrow_forward6-21 Are mixtures of gases true solutions or heterogeneous mixtures? Explain.arrow_forward
- 6-38 Describe how we would prepare 250 mL of 0.10 M NaOH from solid NaOH and water.arrow_forward6-111 As noted in Section 6-8C, the amount of external pressure that must be applied to a more concentrated solution to stop the passage of solvent molecules across a semipermeable membrane is known as the osmotic pressure The osmotic pressure obeys a law similar in form to the ideal gas law (discussed in Section 5-4), where Substituting for pressure and solving for osmotic pressures gives the following equation: RT MRT, where M is the concentration or molarity of the solution. (a) Determine the osmotic pressure at 25°C of a 0.0020 M sucrose (C12H22O11) solution. (b) Seawater contains 3.4 g of salts for every liter of solution. Assuming the solute consists entirely of NaCl (and complete dissociation of the NaCI salt), calculate the osmotic pressure of seawater at 25°C. (c) The average osmotic pressure of blood is 7.7 atm at 25°C. What concentration of glucose (C6H12O6) will be isotonic with blood? (d) Lysozyme is an enzyme that breaks bacterial cell walls. A solution containing 0.150 g of this enzyme in 210. mL of solution has an osmotic pressure of 0.953 torr at 25°C. What is the molar mass of lysozyme? (e) The osmotic pressure of an aqueous solution of a certain protein was measured in order to determine the protein's molar mass. The solution contained 3.50 mg of protein dissolved in sufficient water to form 5.00 mL of solution. The osmotic pressure of the solution at 25°C was found to be 1.54 torr. Calculate the molar mass of the protein.arrow_forward6-19 In each of the following, tell whether the solutes and solvents are gases, liquids, or solids.
