Science anyone?

I'll send you my friend's email who is a reptile biologist.
She's in STT @ UVI and her passion is bats.

She can help you possibly restore your bat populations and give info on how to build bat houses.

I live where we have lots of bats and I have minimal mosquitoes even tho all my screens and courtyard doors are left wide open for dogs to come and go. Only in extreme wet weather that lasts a month or longer do I have to close them. House lizards help, too!;)

Bat Conservation International has bat house plans and much more!

Thanks! It looks like our next project will be a bat house.

My dad's been a member of Bat Conservation International for years. We've had bat house at the family's lake house in PA for decades. The bats always seemed to appreciate them! Lol! We even got dad a bat detector. It's a little transistor radio (showing my age) sized device that turns the ultrasonic echolocation sounds of the bats into sounds you can hear. If you know what you're doing, you can tell what kind of bat. Completely useless for him, but he gets the biggest kick out of playing with it each summer! Lol! The newer models can be fed into a computer and software will tell you the species of bat. A little pricey but if you come from a family or group of friends who are science geeks,....like mine, it's worth it. Lol!

Thanks pdmargie!

PM'd you the email contact.
Good luck !

Here's a great link for info on bats, building bat houses, etc.

Thanks Alana!

Research shows that the larger bat houses are most effective. The bigger, the better. The big ones are used by female bats to brood. The males are more solitary. Small, birdhouse sized bat houses are much less attractive to the females.

Something to think about:

....Was the curvature of light that the astronomers observed in the all important eclipse of 1919, which verified Einstein's Law of Relativity, only an optical phenomenon caused by the water crystals in Earth's atmosphere and that the light near the sun and its gravitational field, in fact, never bent at all? ....

If this is true, what does this mean to Einstein's General Theory of Relativity?

If this is true, what does this mean to Einstein's General Theory of Relativity?

Continuing: Let's put aside the above question, which asks if the Earth's atmospheric shimmer caused light to seemingly look bent behind the sun during Einstein's solar eclipse of 1919, and not gravity as proposed by Einstein in his Relativity Theory.

Think about Mass: Mass is important to the situation. Everything in the universe has mass. Mass is required within the scheme of gravity. Objects with mass have their own gravity. However, it is stated that Light has no mass. If light (photons) is massless, then it can't be affected by gravity, right? If light is massless, it also can't be bent, because without mass light is unaffected by gravity and Einstein said light bent during the eclipse. His witnesses saw it and did the calculations...

Enter Newton and his theory on gravity:

Newton's universal law of gravitation states that every object in the Universe attracts another object with a force that is directly proportional to the product of their masses and inversely proportional to the distance between the objects. According to Newton, two objects in the Universe are attracting one another with a gravitational force that will increase if the distance between them is reduced and decrease if the distance between them is increased.

Enter Einstein and his Theory of Relativity:

General relativity describes gravity as a curvature of space-time. In other words, objects in the fabric of space-time bend it so as to create gravity. Massive bodies like the Sun create a big bend in the fabric of space-time and other objects such as planets simply follow this curvature. IOW, the larger the mass, the more bend in the fabric of space-time; the smallest of masses results in a tiny, tiny bend in the fabric of space-time...

According to theory, light has no mass though. If light is massless, how did it/ does it bend the fabric of space-time? If light is massless, how does it/ did it supposedly bend as proposed by Einstein during that eclipse of 1919? You need "mass" to do all of these things.... do we go back to the shimmer then....?

BTW, this is for fun....

Twinkle, twinkle little star....
So, enter Albert Einstein's Theory once again to propose the answer to the question:

If light is massless, how does it bend due to gravity? (We must also conclude for this purpose that Earth's atmospheric shimmer did not cause the 'bending effect of light' as reported during the eclipse of 1919.) Therefore:

We posed this question to Andrew Pontzen from the University of Cambridge...

Andrew - " Regardless of the mass of the object, the acceleration caused by gravitational pull is the same for any object. Now, Newton came along and gave a mathematical explanation of this and the maths essentially is that mass appears on both sides of the equation which governs this behaviour. So it actually cancels out. A simulated Black Hole of ten solar masses as seen from a distance of 600km with the Milky Way in the background (horizontal camera opening angle: 90°) But if the mass is actually zero, then it’s no longer really mathematically valid to do that cancellation. Nonetheless, it’s certainly true experimentally and mathematically that as you go to smaller and smaller masses, these things are still deflected in the same way by gravity. But since this sort of mathematical paradox of trying to divide by zero, that isn’t conclusive. To get the full mathematical answer actually requires a description of what we call electromagnetic waves, that's the kind of physics underlying the wave light travels, to Einstein’s theory of gravity which is general relativity. Only then do we get rid of this paradox of dividing by zero and end up with a conclusive answer that shows that just as objects of any mass are affected by gravity, so light, which has no mass, is also affected by gravity.

"So in the end, Einstein’s description of gravity, which is general relativity, tells us that the effect of gravity is caused by distortions in space and time itself. Now if you do something as fundamental as distorting space and time, and reshaping it, anything that lives inside space and time will be affected. That includes waves, and so, waves can be bent and can follow different paths if you change the geometric properties of the space they live in. "

A thought still comes to my mind, however: The stars still do appear to be twinkling, don't they?

For our Launch Enthusiasts:
Arianespace launched two commercial satellites for the Americas on Ariane 5 from ESA / ArianeSpaceport in Kourou, French Guiana (Devil's Island, South America).

"On its fourth launch of the year, the second with Ariane 5, Arianespace successfully launched two direct TV broadcast satellites for high definition and 4K ultra high definition services: DIRECTV 15, for the operator DIRECTV, and SKYM-1 for the operator SKY Mexico, a new customer part of DIRECTV Group, serving the Latin American market.

"The Arianespace mission with DirecTV-15 and SKY México-1 is now underway following Ariane 5’s liftoff from the Spaceport in French Guiana.

"Total lift performance for today’s launch was estimated at 9,960 kg., with the two direct-to-home broadcast satellites to be deployed during a flight lasting 37 minutes".

Congratulation, Arianespace!
Enjoy...

Hint: First described by (and named after) British naturalist, Henry Walter Bates, Batesian mimicry refers to the evolutionary tactic whereby a harmless species mimics a dangerous one to keep predators at bay.

No idea what that is !
