hi All

I said to my daughter yesaterday that I she was invisible to me. She replied that because I was touching her I could see her and hence she was not invisible to me. I replied that just because I can touch her does not mean that I can see her. She said her brother could see her, which he confirmed. i said you may be visible to him, but you are invisible to me.

How can she prove that she is not invisible to me?

Make you blink eg by almost poking you in the eye.

[PriniMai]

Even if you saw the chainsaw, it doesn't prove the person's invisibility.

[11Pecepebra]

by asking for a smack around the ears?

well she could hide something behind her, which presumably if you were invisible you would be able to see

I saw that, you sneaky thing! Makes it look like I'm talking to myself

If someone is invisible, they will be blind because their retina will not collect light.
Not a very good superpower.

does invisibility imply see throughness?

Yes. Otherwise the thing is visible.

Unless the invisible thing is refracting light around them so the object behind it isn't visible...

Does invisibility imply transparency though? Something hidden is still invisible.

unintended, but amusing

You mean there might be wiring in top fuelers brain filtering out the image of his daughter, or not placing her image in the right definition/priority box?

kids games are getting complicated

// Does invisibility imply transparency though? Something hidden is still invisible.

Hell no, they are different values of different properties.

Values of (visible) or (hidden) apply to visibility of an element, or its overflow.
The value of (transparent) applies to properties that can take colour values.

Put a candle behind her and a mirror in front of her , sit next to her facing the mirror
a )it shows you can see her and
b) it shows that the light from the candle cannot go through her

[Haremporblape]

she could visually record your behavior around her for an extended period and then analyse your body language for cues to your awareness of her presence


too CSI?

My friend 'Moose' will invisibilise someone for a price.

His actions are quite transparent.

This thread got me thinking about 'visibility' in general.
So whilst not addressing the question " how can my daughter prove she is visible" I thought of some ways we may not see all that is around us or that we can be visually misled.

A part of a recent vsauce youtube video dealt with our perception of colour in the digital world.

Some images here show that things can exist that are normally invisible to us

And here is something you can try at home. Stand close to a mirror. Look first at one of your eyes, then the other. Repeat this several times till you are familiar with the reflected image.
Now, someone standing beside you watching your eyes would have seen that your eyes were moving left and right. So if your eyes did actually move, how come you only saw a relatively still image.
If i underatnd correctly, when your eyes move rapidly the amount of visual data exceeds the brains ability to interpret it
So your brain pauses your 'visual memory' and plugs the subsequent hole in your memory with the first image that it can decode. I understand you can lose up to 20 mins a day of 'visual memory' in this manner.
