While the recommended maximum depth for conventional scuba diving is 130 feet, technical divers may work in the range of 170 feet to 350 feet, sometimes even deeper.
“Low frequency is practical to depths of 2,500 feet,” Cushman says. “Its booming signal makes this a good choice for fishing wrecks in excess of 350 feet, West Coast rockfishing, deep-dropping and daytime swordfishing.” The wider beam angle of a low-frequency model such as the B175L 1,000-watt chirp-ready transducer (about $1,100)—which ranges from 32 degrees at its lowest frequency of 40 kHz to 21 degrees at its highest of 60 kHz—lets you search a wide swath for fish, which proves especially helpful when offshore game like marlin, wahoo and tuna are holding deep.
For example, a AAA battery has a potential voltage of 1.5V, but until it's plugged into a complete circuit, that potential is not realized. — Gnomon
How so? — NOS4A2
There is a philosophical tradition (which I am not totally unsympathetic to) which "answers" questions by consigning them to meaninglessness. It's convenient enough, for all these seeming imponderable questions to be mere misuse of language. We can move on with our life. But what does it mean for these questions, seemingly so full of meaning, to be in fact meaningless? — hypericin
Can this even be, if meaning is in my head? — hypericin
If one takes away the possible forms of their experience and we do not accept claims indistinguishable from the imagination (no matter how plausible), then there is nothing intelligible left: there is nothing to be said about the world in-itself.
— Bob Ross
Again, correct. We can only know of the world in-itself through logical limitations and consequences. Namely, some "thing" must be there. But beyond that, everything is a model we create that attempts to represent what is there... — Philosophim
OK. What kind of philosophical world model, based on what kind of scientific evidence, are you willing to accept as Real? Is that less confusing --- or more? — Gnomon
I think the problem with the answers that brains give though is they are finely contextualized by different personal histories, individual differences in brain structure, noise etc. What people learn and the information they store is probably different for everyone, but in places like academia we want to remove all ambiguity. The side effect of neat clean concepts is they lose all the fuzzy non-linearity which makes them exceptionally good at being used in real life. — Apustimelogist
So, if people like this emerge and write about it, would we even be aware they exist, would we even consider their work? Or are we stuck with slow changes? And by slow changes, I mean derivations from the main method that don't challenge it to the core. — Skalidris
So, what kind of evidence are you willing to accept as Real : physical/material Objects, or mathematical/immaterial Fields? — Gnomon
I subscribed to the Journal of Consciousness Studies for three years and was disgusted by the poor quality of the work. It's not an area of study but a club for people who need to get published. — FrancisRay
The notion of knowledge being contaminated or distorted by human subjects seems absurd given that we are speaking about human knowledge. — Janus
But isn't it exactly the same as we all (?) do when we memorize the standard multiplication tables and recall what 12x11 is. — Ludwig V
(Incidentally, how do you deal with 2 to the power of 35? — Ludwig V
Many famous scientists in history were not atheists or anti religious as your quotes... — Corvus
The word god is for me nothing more than the expression and product of human weaknesses, the Bible a collection of honourable, but still primitive legends which are nevertheless pretty childish. No interpretation no matter how subtle can (for me) change this. ... For me the Jewish religion like all others is an incarnation of the most childish superstitions. And the Jewish people to whom I gladly belong and with whose mentality I have a deep affinity have no different quality for me than all other people. As far as my experience goes, they are no better than other human groups, although they are protected from the worst cancers by a lack of power. Otherwise I cannot see anything 'chosen' about them.

I am an old earth guy but I don’t believe in Speciation. — Isaiasb
Can it be by accident that all birds, beasts, and men have their right side and left side alike shaped (except in their bowels), and just two eyes and no more on either side of the face, and just two ears on either side of the head, and a nose with two holes and no more between the eyes, and one mouth under the nose, and either two fore legs or two wings or two arms on the shoulders and two legs on the hips, one on either side and no more? Whence arises this uniformity in all their outward shapes but from the counsel and contrivance of an author?
other rules like quus. there are probably a multitude of them which are consistent with all of the addition you have ever done so far in your life and you can't rule them out. — Apustimelogist
Our language allows "the" to modify "event," thus indicating the latter is a noun i.e., a thing. Does this syntax present a fallacy? — ucarr
So it remains that "God is truth" and such aphorisms do not convey factual information. Theology, taken literally, is nonsense. — Banno
You imply events are not things. Why aren't they? — ucarr
Picking one example, I say we don't customarily measure the volume (as distinguished from intensity) of our emotional states. Nonetheless we regard them as indisputably real. For this reason, the robust discreteness of scientific truth does not cover the entire spectrum of essential human experience. — ucarr
Simply pointing to an object and uttering simple words sound like a limited elementary ability of language use by young children just starting to learn languages rather than key ability for the general language users. — Corvus
Because I am speaking on the desire to not allow a higher power to have any basis over them. — Isaiasb
I didn't believe in Absolute Truth but I was confident in my beliefs. — Isaiasb
Agnostics and atheists alike fight for their belief in nonbelief, and their desire to be contemptuous in believing nothing. — Isaiasb
Ironically I have been an atheist longer than I have a Christian. — Isaiasb
Then enlighten me on what they think. — Isaiasb
For a few reasons, the biggest is that it is a new thing. For all of human history until the last century Atheism was seen as something that is false. Atheism fights a God they don't believe in. In doing so they replaced God with Science, and in doing so they don't have to worry about a higher power with higher morals. — Isaiasb
Agnostics and atheists alike fight for their belief in nonbelief, and their desire to be contemptuous in believing nothing. — Isaiasb
There is already an amount of research around replicating microorganism behavior with a combination of logic gates - which is the fundamental computational mechanism in electronics. Example nice read:

I think the reason no one has challenged the minor is because we all believe that we possess a knowledge of our acts which is not mediated. This is different from our knowledge of the acts of others.
— Leontiskos
If all knowledge of action is mediated by neural processes, then we may well all be mistaken in thinking that we possess non-mediated knowledge of our own actions. We "feel" our own actions "from the inside" it seems, and we see, or hear the actions of others, but if feeling as well as seeing and hearing is mediated by prior neuronal activity, the immediacy may be merely phenomenological, which then just be to say that knowledge of our actions seems immediate, which is of course true. — Janus
I'll point out, however, that Koch is a neuroscientist, and he also says they can't explain it. — Patterner
Greene doesn't give a non-robust scientific explanation. — Patterner
That is all consistent with idealism. — RogueAI
Why should we suppose there exists a physical brain made of non-mental stuff? — RogueAI
All good examples. They're all about the information processing aspect of cognition, however, and leave open the possibility that this functional level of consciousness is superficial. I was being sloppy suggesting there is no evidence,and should have said no overwhelming evidence. — FrancisRay
There is no physical experiment that could prove consciousness has a physical basis, and while this does not prove it doesn't it might be argued that it's an unscientific claim. What would be your view on this? — FrancisRay
