Here we met a set of sets.
The set of subsets of a set, can only be, of course, a set of sets.
The set {2, 21, 14} is a set of numbers. The set { { }, {4, 78,
56} } is a set of sets. It has two elements: the empty set {}, and
the set of numbers {4, 78, 56}. Do not confuse a number, like 24,
and a set, like {24}, which is a set having a number has elements.
In particular it is the case that {4, 78, 56} belongs to { { }, {4,
78, 56} }. Take it easy, and meditate on the following exercise:
Which of the following are true
{3, 5} included-in {3, 5} True
OK.
{3, 5} belongs-to {3, 5} True
Not OK. The elements of {3, 5} are 3 and 5. {3, 5} is not an *element*
of {3, 5}.
Ask in case you are not OK with this, of course.
{3, 5} included-in { {3, 5} } False
OK. Very good.
{3, 5} belongs-to { {3, 5} } True
OK. {3, 5} is even the *only* element of { {3, 5} }
No exercise today. Just a question, a suggestion, and a plan.
The question is: have you the feeling to learn something?
The suggestion: I think the best way to answer the preceding question
consists in trying to explain what you learn to someone else. It is
the best way to see if you remember and understand the definition. You
could try to explain what you learn to some gentle victim in your
neighborhood (wife, friend, child, parent, ...).
I give you a plan, and some more motivation. To get the seventh step
in some proper way, there is a need to understand the mathematical
notion of universal machine. For this I need to explain what is a
computable function. For this I need to explain what is a function,
and for this I need to explain what is a set, given that functions can
more easily be explained through sets relating sets. Once you will
have a good grip of what is a universal machine, or what is a
universal number, and what really means universal, we will be able
to tackle the notion of universal dovetailing, and especially the
mathematical universal dovetailing (which is really important for
the whole approach, and for the step eight). I am hesitating to work
quickly on the notion of function, or to do some pieces of number
theory and geometry to provide examples before.
As I said recently to John, the discovery of the notion universal
machine is one of the most astonishing and gigantic discovery made by
the humans, and what I do is just an exploitation of that discovery.
Universes, cells, brains and computers are example of universal
machine, and the notion of universal machine are a key to understand
why eventually, once we say yes to the doctor, and believe we can
survive qua computatio, we have to redefine physics as an invariant
for the permutation of all possible observers, and how physics can be
recovered from an invariant among all universal machines point-of-
views ...
Feel free to slow me down, or to accelerate me, and to ask any
question at whichever level of details you want. Feel free to ask any
question that you have already asked.
Have a good day, and thanks for your effort and seriousness,
Bruno
PS. It should be obvious for everyone that if there are still
questions, critics, objections, problems, feeling of dizziness,
whatever, with the first six steps of the UDA, please, feel free to
ask. And people should not hesitate to discuss other everything-like
subject, I don't want to monopolize the list of course. But the UDA
reasoning really changes the perspective on all possible TOEs, so I
will feel free myself to point on UDA on each discussion where I find
it relevant (of course also).

I've read about Turing machines if that's what you're referring to.
For this I need to explain what is a computable function. For this I need to
explain what is a function, and for this I need to explain what is a set, given
that functions can more easily be explained through sets relating sets. Once
