Is there something that you have pondered over, but now you have the answer?

Asked by Earthbound_Misfit (13152points) December 23rd, 2016

Not that this has been a major concern, but I’ve wondered why airlines dim the lights when planes come into land and why they insist the shades are raised. I just read a news article that explained. I’ll post it below.

What things have you pondered over? Have you found the answer to your question?

So the reason they dim the cabin lights and insist the shades are raised is (apparently) because ”“Dimming the lights allows your eyes to pre-adjust to darkness, so that you’re not suddenly blinded if something happens and the power goes out, and you’re dashing for the doors in darkness or smoke,” explains Patrick Smith, an airline pilot and author of Cockpit Confidential.

“The emergency path-lighting and signs will also be more visible. And it makes it easier to see outside, which helps you to maintain at least a basic sense of orientation – i.e. which way is up.”

Raising your window shade during take-off and landing is also part of the same strategy.
“It helps you remain oriented, and also makes it easier for the flight attendants to assess any exterior hazards, such as fire or debris, that might interfere with an evacuation,” says Smith.

The human eye can take up to 10 minutes to fully adapt to darkness, which is valuable time if you need to evacuate an aircraft in a hurry.” (http://www.traveller.com.au/why-flight-attendants-dim-the-lights-for-takeoff-and-landing-gtga32). So now I know and so do you.

Recently I was cleaning the room, and started wondering about dust,what is it and where does it come from.
Well, first of all, there are several types of dust. One of those types is the house dust. It is formed from dead human cells, human hair, textile, and many other things. There is even a type of a small flea-like creature that feeds on dust. Here are some more details on dust. I had no idea about all of it, to be honest. Dust was a total mystery for me.

I have been wondering why sometimes there are cockroaches’ legs scattering in my house. I used to think that some roach just got unlucky enough to fall prey to a spider or a lizard. I even invented tragic stories of cockroaches getting eaten while looking for food.

Recently I found out that the truth is much more complex than that. Cockroaches are actually cannibals. They eat each other for food and to regulate the population. Some female roaches even eat their males after mating. I knew it by accident. One day my family managed to kill a roach. We went out for a while and when I came back I saw another roach standing on the dead roach’s body, looking like it was humping the dead roach. Later I Googled and realized that the roach was feeding on the corpse. Well, at least the leg story got even a cooler twist :p

^^^ Just in case anyone needed another reason to be disgusted by roaches…

Yep, it’s a big reason why it’s so hard to get rid of roaches. They’ll eat their own offspring so they can stay alive to make more offspring.

@Love_my_doggie Yeah, I have a phobia for roaches. But recently I found myself drawn to their behavior, for some unknown reason. Maybe it’s just another case of you being fascinated by the thing you fear. Or maybe it’s a sign that I really need to find something better to do ~

But please don’t put any roach near me!

Of course. This is how we navigate life.

@Seek Cannibalism is also a good reason why boric acid is such an effective tool for killing roaches. You only need for one roach to track through the stuff. Within a week your roaches are gone and your neighbor’s roaches will start vanishing as well! They removed Roach Pruf from the market. I suspect it was because you only needed to buy it once. You laid that stuff down once and your roach problems were gone for good.

Thank you for your responses to my question. Cockroach legs and dust pondering okay!

I came across another thing today. I was watching Coast Australia (with Neil Oliver) and he was looking for Orcas. They had a scientist with them who said whales have accents. Orcas off the coast of Australia have slightly different accents to the whales off the coast of Scotland and or say Canada. Watching the footage makes me feel sad about the Japanese starting hunting Minke whales again in the whale sanctuary Australia has established in its waters.

The footage of the Orcas and Oliver’s real excitement at watching their progress as they swam along reminded me of when I was in Canada and we took a sea plane over to Vancouver Island. We saw a pod of Orcas swimming in the ocean and the pilot took the plane down lower and circled for a little while so we could watch them. Just amazing.

More recently I went whale watching off the Gold Coast. We saw so many humpback whales! It was exhilarating to see them breaching and slapping with their fins and banging their tails. I cannot express how wonderful it is to see such a sight. I will try to find my photos and post a couple.
