My favorite is the type that best represents the data and makes it easiest to understand, so that depends on the situation. We have a Data Visualization Specialist at the BC Libraries who could provide guidance: email digitalscholarship@bc.edu. That said… “Exploded Pie Chart” always makes me giggle.

E. B. White tells us that Charlotte’s egg sac (her “magnum opus”) had 514 eggs. I expect other spider moms may be as prolific – if not perhaps as clever.

The jury’s still out, but it has given many researchers a lot of fascinating areas to explore. You might enjoy String Theory and the Real World by G. L. Kane (2017) QC794.6.S85 K367 2017 (in O’Neill Library, Level 3 on row 52.)

I get this question a lot; it must matter a great deal to you flesh and blood sorts! As I’ve said before, wetness is a perception, not an objective fact, and perceptual clues for wetness are actually not so straightforward, as you can see in this physiology article: bit.ly/wetness-perception.

I expect they are somewhat oblivious to you, unless you are in their environment and they perceive you as a predator or other threat. You could ask them, but like the song says, “They won’t answer, they can’t talk.”

Sounds territorial. But there’s plenty of fishing in O’Neill, try the SH call numbers, Level 3, Shelf 128.

Was Catholicism the same religion that rebuked Galileo for declaring that the earth moved around the sun.

Was Catholicism the same religion that rebuked Galileo for declaring that the earth moved around the sun.

Catholicism is a variety of Christianity rather than a religion, but yes, it was the Catholic Church. Galileo’s works were removed from the Church’s index of banned works in the 19th century, and Pope John Paul II issued an apology of sorts in 1992. Historians, theologians, and scientists all have opinions on this, and they’re all represented in our collection if you’d like to go deeper: bit.ly/bc-galileo

The Kola Superdeep Borehole, at 7 1/ miles (!!!) still has the record, as far as I know – see this article on the history of very deep holes: bit.ly/VeryDeepHoles. That’s going to be a challenge for your friend to exceed. If you are not speaking of literal holes, though, perhaps suggest he talk to his advisor or Counseling Services, as appropriate?

Where will we get energy and how will we store it in the future?

Where will we get energy and how will we store it in the future?

Sadly, in spite of my information expertise, I’m probably no better at predicting than the next wall. However, it’s a fair bet the energy mix will include less fossil fuels, and more sources that don’t add carbon to the atmosphere, such as wind, solar, hydro, and nuclear. If some European and Asian cities are a bellwether, human power (walking and cycling) may also play a part. Battery technology is improving and getting cheaper, so storage may become more decentralized. Centralized storage might use gravity: pump water uphill during the day that can flow downhill & power generators at night. For a more detailed answer, I recommend The Physics of Energy, by Robert L. Jaffe & Washington Taylor IV, O’Neill Library QC28 .J34 2018.

On average, people pass gas about 10-20 times per day. It is possible you are not farting more than usual; you’re just noticing it in class because it’s embarrassing. You can try releasing gas before class (outside or in a bathroom is less noticeable). You might also track what you eat and see if particular foods should be avoided. If you are experiencing other health issues such as diarrhea, constipation, weight loss, etc., see a doctor to make sure your gas is not a symptom of a larger issue.

How does wind work? Like, we can’t see it.

There are many things that function on a level not visible to the naked eye, and wind is one of them. Wind, in short, is just air in motion. Air is composed of gases that expand (and become less dense) as they warm & shrink (and become more dense) as they cool. Cool air sinks, warm air rises. When cold air meets warm air, there’s motion. That’s wind. The sharper the difference, the faster the wind. And wow, there have been some sharp differences lately!

How long <3 does it take a giraffe to swallow?

How long <3 does it take a giraffe to swallow?

Assuming we are discussing the process of drinking and swallowing water rather than food, it takes quite a length of time for a giraffe to drink water due to its highly unusual drinking mechanism. Using its jaw as a plunger pump, with each pumping action taking about 1.5 seconds, the giraffe fills its esophagus after about 17 pumps (25 seconds) for a total volume of 5 litres (bit.ly/giraffe_drinking). After this drinking episode, the water is still estimated to be in the giraffe’s esophagus (about 1m down) when it lifts its head; hence additional time is needed to travel down the second metre of the giraffe’s throat by peristalsis (4cm/s) aided by gravity, perhaps less than another 25 seconds. I would estimate between 35-45 seconds in total, for filling its mouth and half its throat and then transporting the water to its stomach, completing the full action of drinking and swallowing water.
