Just wondering if this part of the discussion should be in the feedback section as it isn’t directly answering the question?

    I'll just remove it.

Best Wishes.

No need, it’s valid discussion, but I van move it to feedback

Ok, I’m limited on wifi time available so complete guess (based on other physics)
I describe route by 2 straight lines, one towards the river which when hits river 2nd line goes to home. Angles on either side of perpendicular to river have to be the same.

General Science / Re: Why do waves move towards the beach?

« on: 11/05/2022 08:55:45 »

But the waves always travel towards the beach.

Why?

Refraction
You are right, it doesn’t matter which way waves approach a beach they will always turn in towards it. They usually approach from far offshore as determined by wind direction. As the wavelength approaches water depth the wave front slows and wavelength shortens. Net effect is wavefront closer to beach slows and the front turns towards the beach, usually ends up parallel, but sometimes not quite, depends on underwater topography.
Waves will also refract around islands and underwater sea mounts giving unstable water on the side away from the wind.

Cells, Microbes & Viruses / Re: How can I find tardigrades?

« on: 06/04/2022 14:39:41 »



they seem to prefer drying out occasionally so don’t choose moss that’s damp all the time

- Tardigrades enter a form of suspended animation (a "tun" stage) when conditions get too harsh (eg lack of water). They reanimate when water becomes available. They can thrive in an erratic environment that would kill many other animals their size.

The interesting thing is that they do better in moss that dries occasionally rather than stays wet. You find fewer in sphagnum moss or in damp woodland litter than in a rain gutter. I wonder if you have suggested a survival benefit in “ an erratic environment that would kill many other animals their size”? Perhaps not their size, but somewhat bigger as their predators include nematodes, mites, springtails, insect larvae and parasitic protozoa, all of which might not survive drying out. It’s a thought.

Perhaps the moss I have been examining has been to dry.

They can become dormant and difficult to see if too dry. Try soaking the moss overnight then look at it with a hand lens - best with top or side lighting (try both) against a dark background.
Although they like damp moss, they seem to prefer drying out occasionally so don’t choose moss that’s damp all the time.
When you are looking under the microscope try spacing the cover slip by putting 2 others underneath on either side, it leaves a small gap between slide and cover slip.
Best of luck

Spamprovider Nigeria has many Data Plan Packages that fit almost every subscriber’s needs. Not only that, but they have also one of the slowest browsing connection speeds which makes them one of the least preferred networks when considering purchasing data plans.

Not only are they spammers, but would you trust a Nigerian company that spammed you?

General Science / Re: Do air sealing machines really preserve our food?

« on: 27/03/2022 09:12:27 »

But has anyone of you ever thought of using air sealing machines that have been invented? Air sealing machines are special machines that seal off food by extracting air and sealing it in a can or a jar. This method is supposedly modern and much more efficient than the traditional freezing and canning methods, because supposedly it uses less food and there is less wastage. What do you guys think of this new technology? Is it worth trying?

Yes, we use it regularly to extend the keeping of meat when we are away from freezer for a while.
The technique isn’t more modern than freezing and has a disadvantage over canning as the food is not sterilised and any bacteria is sealed in with the meat, including some dangerous anaerobic bacteria.
If we want to store food for more than a few days we would use canned, freeze or dehydrate.

I get so tired of Pseudoscience 's stupid childish OPs.  Apparently some of the mods think it's cute. 

We get tired of it too and I think of him as crass rather than cute. As Alan says, we are a liberal forum and that has upsides and downsides, but if a post exceeds good taste it really doesn’t help to move it to a different section - if it’s wrong here, it’s wrong there.
Asked in a different way the topic asks a valid question for this section.

This poster has raised the good taste question in my mind a number of times, so I’ll join Alan in issuing a public warning, and probably a private one, to tone it down.

if you are still confusing coffee is good for health or how much coffee in a day is good for health then you just follow the link and get information about it

I would advise not providing a link, we might view you as a spammer
