Inertial frames cannot exist.

I think that inertial frames are impossible.

A true inertial frame is an object going a constant speed in a certain direction. There has to be zero acceleration on the particle. In other words, there has to be no force acting on that particle.

However, on a matter particle there will always be a force. Gravity has infinite reach, so no matter how far away you are from matter, there is always a nonzero force acting on a particle. This leads to a nonzero acceleration, which makes the inertial frame non-inertial.

Even a particle without mass can’t be in an inertial frame! Since gravity acts even on light.

 

Symmetry, entropy and information

Something is symmetric if there is an operation that leaves the system unchanged.

A square is more symmetric than a rectangle, since the rectangle has one axis of reflection and a square two.

Something that is higher in symmetry needs less information to describe it.

For a square you need one number: the side. For a rectangle you need two numbers, two sides.

Entropy is the degree of missing information. Something that has a lot of entropy has a lot of missing informaiton.

Assymmetries create information.

Entropy is the measure of the amount of information needed to describe something.

Information

By gaining information about the position of a particle, you lose information about it’s impulse. You cannot simultaneously have all the possible information about the position AND the impulse of a particle.

It feels like they are orthogonal vectors or whatever. For example in different inertial frames, you can describe an event with complementary space time coordinates. Less spatial coordinates means more temporal coordinates.

The reason is because the mechanism to gain information about the position of a particle destroys information about the impulse and vice versa.

Mechanism

To gain information about you have to shine a light on the particle with a higher frequency. A higher frequency provides a higher contrast, or higher pixels. The contrast or pixels are determined by the wavelength. Shorter wavelength means higher frequency. However this means a higher energy and impulse as well.

Maximum information contained in a volume.

Also there is a maximum of entropy to a volume of spacetime. This maximum is correlated/proportional with the surface of the volume, instead of the volume. This is a weird concept. It does surface in the inverse-square laws.

Information is on the surface, not in the volume

When are you someones friend?

If you have the capability to insult them as friends without actually making them feel insulted. When they realize you mean it in a funny way instead of real.

Evolutionary basis of depression and anxiety disorders

The reason these disorders exists in this high prevalence is because it weeds out bad genes in a population.

Depression:

Depression is usually the result of strongly feeling a failure at something or being social excluded. If every organism in the herd has a certain internal signalling system to remove themselves from the population in the case of failure, it will leave the population in a better and stronger state.

Becoming depressed after failure or social exclusion removes the genes that caused that failure. It is healthy for the population to have individuals capable of becoming depressed. However, it is very sad and terrible for the individuals themselves.

Maybe understanding this mechanism can make people feel angry at it and want to overcome this internal mechanism.

 

 

Our evolutionary behaviors are not inherently non-ethical programmed..

Often people see evolutionary theories extremely egocentric or individualistic. That our genes want us to do non-ethical behavior. Such like cheating, murdering, being egocentric, being mean. The strongest have to survive. This can be the case for certain organisms.

In the case of humans, contrary to popular belief, this is not the case. We are deeply social. Just like ants, we are part of a super-organism. This means that altruism, caring for one another, feeling a family and united, are deeply rooted in our evolutionary biology. Being good, being ethical, sharing resources are not against evolutionary programmed behavior, but are actually one of the distinctive properties of human evolutionary biology.

Nietzsche for example said that according to science, every person has a will to power. I do not argue with the fact that will to power exists in humans. Nietzsche also argues that preying on the weak is not inherently non-ethical. He says that it is our nature. However, I argue for the beautiful and comforting thought that this is actually not the case at all.

About conversations

 

Having good conversations significantly improves your quality of life. Try to infect people with your happiness.

Conversation Paralysis (CP) is the inability of a person to start or sustain a proper conversation or join an existing conversation in a graceful manner.

An example is with colleagues in the coffee break. A conversation is held between the people.

How do you join such a conversation gracefully?

How do you add to the conversation in a positive way?

How do you come up with a fruitful subject (FS). A fruitful subject will grow out of the common ground (CG) with a person.

Ways to start a conversation:

1. Friendly Greeting (FG): “Hi, Jen, it’s good to see you.”
2. Remark-Question technique:

When trying a new FS the following things are of importance:

1. Timing. Don’t interrupt.

List of subjects to talk about:

1. Surroundings
2. Weather
3. Remembering stuff about people
4. News
5. Something that was on TV that other people could have watched.
6. Location or Occasion
7. Pets
8. Other people (WARNING, DARK SIDE)
9. Where do you actually come from?
10. What was your highlight of the day? No, well than we’ll have it now.
11. Travel stories.
12. The person that you are talking with.
13. Music, do you play any instruments?
14. Food: What is your signature dish or tips.

List of stuff you can ask questions about:

1. Particular stuff of people
2. “How is it going?”
3. What are your plans for the weekend?
4. Location of Occasion

The conversation quality (CQ) is dependent on the following things:

1. Genuine laughter
2. High proportion of interested conversing participants.
3. Lack of awkwardness
4. Lack of negativity

The conversation usually is automatically of higher quality because of the following characteristics of the participants of the group.

1. Similarity
2. How often you spoke to them

List of fun questions:

1. If you won the lottery, what would you do?

Essential abilities:

1. Be an active listener (AL).

Demonstrate that you are engaged in the conversation. This makes the other person feel valued and respected, which heightens the conversation quality.

Say their name to adequately get their attention.

Be a nice gossiper. When gossiping talk about the other persons in a positive light. People love to gossip and showing that you gossip positively

Paraphrasing is essential in being an AL

Humor is the salt and pepper to life. Be Anti-Boring.

Keep things light and positive.

The time frame for anecdotes out of the blue is around a week.

Nonverbal language is essential

Exude confidence and be determined. Nervousness will infect the other person with negative feelings. Boldness is important in conversations. If you see the conversation as a minefield, it will be a minefield.

Look approachable by having an open body posture. Try to stay relaxed. Introduce yourself to people. Keep it during the conversation. You can always do this, because it does not require conversation skills!

Eye contact – no eye contact

Open body posture – closed body posture

Giving cues of understanding (nodding, humming, shaking)

Use expressive gestures to become more central.

Duchenne smile (DS). Smiling with your eyes.

Be curious or fascinated by people. This drives yourself to question about people.

Having great anecdotes in your pocket are nice handgrenades for fun conversations.

Stay interested and engaged in the conversation. Put a unique spin to the conversation.

Have an interesting life for interesting conversations. This is the basis for fruitful anecdotes and people being interested in you.

If you’re consistently unable to connect, it’s possible that you just aren’t expressing your interests well (whether by under- or over-sharing) or that you’re hiding those interests out of fear that people might reject them (and you). The end result – no relevance and no connections. At some point, you have to be interested if you want to be interesting.

Mirror.

How to make it awkward:

1. Over-sharing. This results from nervousness.
2. Avoid the RAPE subjects: Religion, Abortion, Politics and Environment. Also includes Relationships and Sex. Money.
3. Do not laugh too much.

Compliments

Compliments can be a great way to instantly start a great positive conversation:

1. I like your handbag. Where did you get it?

Self-Talk:

Interestingly, mastering Self-Talk is important before mastering talking with others. For example, not coming up with FS’es can be because of High Filtering (HF). This is the tendency to disagree with saying whatever that comes up to you. Being very nervous or self-conscious destroys your capability to introduce a nice flow to the conversation.

The biggest conversation-killer is self-consciousness. Don’t worry about saying something stupid; it happens to all of us at some point. The worst thing you can do is to not speak up when there is a fitting opportunity.

Keep the questions as open as possible:

• Closed questions: “Do you like books?”, “Have you ever been to this university?”, “Is spring your favorite season?”, “Am I intruding?”, and “Do you come here often?”
• Open questions: “What sort of books do you like?”, “What did you study here at this university?”, “Which is your favorite season? Why?”, “What are you doing right now?”, and “Where’s your usual watering hole?”

The Remark – Question Technique:

• “That’s a nice handbag, where did you get it?” This lets the handbag owner talk about the day that they went shopping and all this funny stuff happened, as opposed to: “I like your handbag!” “Thank you.” (The end.)
• “What an amazing buffet! Which is your favorite dish?” Asking an opinion is especially useful, as it can be followed up with the classic open-ended question: “Why?”
• “Fantastic turnout! Which of the lecturers is your favorite?”
• “I love your costume. What are your favorite sci-fi movies?”

Nothing and something

All the numbers are just representations of collections of nothing. This sentence makes no sense, but I’ll explain it:

Imagine the set of nothing. It includes the following element: zero. However, the set is not empty, it contains 1 element. De set that includes nothing and the amount of elements in the set nothing contains 2 elements. And so forth.

We can create something from nothing by putting parentheses around it. A border. We can count it.

In this ridiculous way you deduce with sets of nothing all the numbers.

Lowering of temperature reduces symmetries

Update: I actually think the reasoning is misguided. If you lower the temperature of an object, it gets more homogeneous and a lower entropy. A lower entropy means that you need less information to describe it. Something that is high in symmetry needs less information to describe it. That would mean that cooling an object heightens the symmetry! Hopefully I can clarify this post in the future.

Something is highly symmetric if there are a lot of operations you can do on that thing that leaves it in the same state.

Reducing the heat energy of a system reduces its symmetry.

For example:

The big bang. A hot plasma with a unifed theory of everything reduces to galaxies and four forces.

A pencil on its tip: It falls over to a lower energy-state and reduces its rotational symmetry to nothing.

Water: When it is cold enough it becomes ice and the symmetry of the water reduces to crystals.

Lower energy equals less symmetry.

The more homegenous something is, the more symmetry it has.

Is something completely homogeneous 100% symmetric? And is a completel homogeneous condition ‘nothing’ because you can’t compare it with anything?

A calendar and a map measure the same thing.

First mindblowing thought:

1. A calendar and a map measure the same thing: Spacetime.

Before 1900’s time and space were understood to be nothing alike. The first hints dropped that time and space are two sides of the same coin were done during the electromagnetic experiments in the 19th century.

What does it mean that time and space are two sides of the same coin? It means that what one observer experiences completely as time, someone else experiences as a combination time and space. Light even experiences that time completely as space!

Equivalent is explaining the size of a tv in terms of diagonals or width and height. Different numbers that capture the same thing: the size of a tv.

Second mindblowing thought:

2. The only way you can measure something is with a calendar and a map.

Every unit is either a composite of meters, seconds or mass. But we measure mass by its effect on for example a spring. So even mass is measured by either meters or seconds.

A calendar and a map are more symbols for the meters and seconds.

Third mindblowing thought:

3. Only what can be measured is real.

In reality we only experience spacetime.
