The principles of deep work, coupled with actionable rules and strategies, offer a roadmap for individuals striving to thrive in a world that often prioritizes being busy over meaningful productivity.

Book Summary - Range by David Epstein

Introduction

I have just finished reading the book Range by David Epstein. I thought it was very good hence I thought I would share my notes.

You should read this book if you are interested in personal development or skill development. It argues against the common belief that early specialization is the best way to learn.

Book in three sentences

Range is better than early specialization. Sampling lots of skills and experiences before specializing can lead to greater success in the long run.

Range helps us think critically and solve problems. Having a broad range of knowledge and experience can help us to see problems from different perspectives and come up with creative solutions.

The generation effect is important for learning. Struggling to find the answer on your own, even if you get it wrong, can help you learn more effectively.

Full Summary

Deliberate practice is good, but might lead to a narrow perspective. It might be better to develop 'range' by sampling lots of skill and experience to start, then specialise later. We need 'range' to function more efficiently in our ever growing world of complexity. Range may be a disadvantage at first, but in the long run may benefit you more than early specialism.

Deliberate practice works extremely well in kind learning environments, were problems and answers are well defined and we can develop chunking. Deliberate practice fails with wicked problems where connections between problem is difficult to define and answers are not certain. For wicked or real life problems we need range. Range is needed to make creative breakthroughs.

Range gives us the ability to think critically about problems and form abstract concepts. Specialist learning is fragile outside it's area of specialization. We need to be able to bring the thinking from one area into another. We need to learn how to think not just learn facts. The world is getting smarter as peoples range increases.

When learning it had been seen that dedicated practice from a young age only produces someone who is good not someone who is top of their field. People who are top of their field sample lots of things before specialising. The good practice on one instrument and one type of music. The top play multiple instruments and multiple styles. They have range. We learn our native languages informally and play with it making mistakes. We do this before we start to learn it in the class room.

The Generation effect has been shown to have the biggest impact on learning, that is struggling to find the answer on your own, even if you get it wrong. Struggle is more important than repetition. Spacing (increasing the time) between practice and Interlving (doing something else) can help make the learning harder and hence more effective. It is important to struggle and not get any hints. Hints hurt your learning. It may seem that you are making slower progress at first, but in the long run this will be better for you.

To solve wicked problems you need to use Analogical thinking. You need to look at the non obvious connections to other domains. Start solving a wicked problems by thinking about different analogies from multiple different domains.

Additional thoughts

• Don't be afraid to try new things and explore different interests.
• Don't be afraid to fail. Failure is a natural part of the learning process.
• Be open to different perspectives and ways of thinking.
• Be curious and ask questions.
• Don't be afraid to think outside the box.

Understanding the SIGMOID Activation Function

 

SIGMOID Activation Function

When we are building a neural network almost always the function we want to model is not linear in nature. To deal with this we need to use an activation function which introduces non-linearity into the neural network. A common activation function uses the SIGMOID function, define by the equation below.

For a given value of x the SIGMOID function will produce an output between 0 and 1. We can demonstrate this with the following R code.

library(ggplot2)

 

# Define sigmoid function

sigmoid <- function(x) {

  1 / (1 + exp(-x))

}

# Generate data

x <- seq(-10, 10, length.out = 100)

y <- sigmoid(x)

 

# Create data frame

df <- data.frame(x = x, y = y)

 

# Plot sigmoid function

ggplot(df, aes(x, y)) + geom_line() + labs(title = "Sigmoid Function", x = "x", y = "y")

Adding a weight to the SIGMOID

By adding a weight W to the sigmoid equation we can vary the gradient of the slope between 0 and 1, as shown but the R code below.

library(ggplot2)

 

x <- seq(-10, 10, length.out = 1000)

 

# Define sigmoid function

sigmoid <- function(x) {

  1 / (1 + exp(-x))

}

 

# Generate sigmoid curves for different constants

constants <- c(0.5, 1, 1.5, 2)

curves <- lapply(constants, function(c) sigmoid(c * x))

 

# Plot the curves

ggplot() +

  geom_line(aes(x, curves[[1]], color = "0.5")) +

  geom_line(aes(x, curves[[2]], color = "1")) +

  geom_line(aes(x, curves[[3]], color = "1.5")) +

  geom_line(aes(x, curves[[4]], color = "2")) +

  ggtitle("Sigmoid Function with Varying Slopes") +

  xlab("x") +

  ylab("y") +

  scale_color_manual(values = c("0.5" = "blue", "1" = "red", "1.5" = "green", "2" = "purple")) +

  theme_bw()

Bias connection

We can add another input to the activation function called bias input. Bias input is always one multiplied by a weight b. The purpose of the bias input is to move the sigmoid function either to the left or to the right as by the R code shown below.

sigmoid <- function(x, bias) {

  1 / (1 + exp(-x + bias))

}

 

# Set up plot

plot(NULL, xlim = c(-10, 10), ylim = c(0, 1), xlab = "x", ylab = "y")

 

# Plot sigmoid curves with different biases

curve(sigmoid(x, bias = -3), add = TRUE, col = "blue", lwd = 2)

curve(sigmoid(x, bias = 0), add = TRUE, col = "red", lwd = 2)

curve(sigmoid(x, bias = 3), add = TRUE, col = "green", lwd = 2)

 

# Add legend

legend("topleft", legend = c("-3", "0", "3"), col = c("blue", "red", "green"), lwd = 2)

Logistic Regression

The Sigmoid function can be used to calculate logistic regression. This kind of regression is used to calculate the probability of a binary outcome or decision based on the input.

The Paradox of Time Management: Why Slowing Down and Being Choosy is the Key to Success

 

Introduction

I was thinking about time management, and I remembered a concept that was on the tip of my tongue, but I could not quite articulate it. This led me on a search, and what I discovered were some notes I made in May of 2022 from reading the book 4000 hours by Oliver Burkeman. The following is my attempt to flesh out my notes into something more readable. But if you have time, I urge you to read the book, it is excellent. 

Summary

• It is natural to never get to the end of your to-do list.
• Slow down.
• Be discerning about the tasks we do.
• We need to be more choosey about what we take on.
• Celebrate not being able to do it all and say no to most things.
• What we achieve is down to chance.
• Pay yourself first. 

Delusion

Are we deluding ourselves? Will we ever get to the bottom of our to-do lists?  We all have a finite life and as a society we are trying to cram in more and more, we aim to be highly efficient and be as productive as possible. This goal of becoming our most efficient and effective self’s is draining the joy out of life. 

It seems to me that the more we tick off our to-do lists the bigger and not smaller our lists get. This paradox tells us that we need to admit defeat and acknowledge we will never get everything on our to-do list done. If you had a fairy godmother who could magically disappear all the things on your to-do list, then miraculously by the end of the week your list would be just as full as it was before the magical intervention occurred. What we need to do is change our relationship with the things we have on our lists. 

Slowing down and being more discerning

Time is an abstract concept. We split our life up into buckets of time that do not actually exist. This process of putting time into buckets is the source of our stress. A large number of us measure our self-worth by the number of things we can tick off each day. This act of speeding through our lists is an act of avoidance, we are trying to ignore our fears. 

But it is impossible to master time, we will never complete everything on our lists and most of the tasks we complete aren’t going to make any difference to the grand scheme of things. Taking control of your list is not done by speeding up, but by slowing down and being more discerning about what we do. 

Oliver Burkeman said that the paradox of limitation is the more you try to manage your time to get the feeling of total control, the more empty and frustrating life gets. But the more you confront the fact we have limited time and work with it the more meaningful our lives can become. 

The only power is choice.

Busy, we all have too many things to do than we can fit into the available time. Not being able to fit it all in is making us feel overwhelmed. To make matters worse we should not feel guilty for not fitting in everything, but we do. 

Efficiency is a trap, the better our productivity system is at giving us time the more we fill it with more and more tasks. This is the effect known as Parkinson’s law, our jobs expand to fill the available time. All this means is we live under the illusion that one day we will get everything done. 

The only thing we can do is choose. We can only choose to do a few important things and deal with the fact that the other things will not get done. Our life is finite and this means we can only do a finite amount of things. Our only power is choice.   

Celebrate finitude.

I like the word finitude. It reminds us to make the most of our time and appreciate the fleeting moments that we have. Finitude is the quality of being finite or being limited by bonds or scope. This means that every time we make a choice to do something (or not do something) we define who we are. 

If finitude did not exist and life went on forever, there would be no need to make any choices and life would stop having meaning. The fact that we cannot do everything is therefore something to be celebrated because it makes us unique and gives us a reason to make the most of our finite time. 

Get better at not doing things.

The point of a time management system is not to get better at doing things, but to get better at not doing things. If we accept we can not do it all, then we need to stop acting as if we can. We need to stop feeling guilty about what is not getting done.

We need to commit to a few things and achieve them. This needs to be done in a way that does not leave us riddled with guilt. The three best strategies for doing this are:

·        Pay yourself first: Schedule time to get your pet projects done first.

·        Limit your work in progress: Only have three active tasks open at any one time.

·        Resist middle priorities: Focus on your top five priorities and ignore the rest. 

Enjoy Boredom.

Stop wasting time. We are all easily distracted, but the distractions are stealing our time. In the end watching the cat video on YouTube will not make us more fulfilled, this type of activity will just waist precious moments of our life that we can never get back.

 What we focus on will change how we experience it. This means if we focus and work harder at something we find boring in the end we will come to love it. Don't resist the pain of being bored, work through it. Ironically sometimes the solution to boredom is just to accept that sometimes we will get bored, live with it. 

It's all down to chance.

Hofstadter law - It always takes longer to do something even if you take into account Hofstadter law. This is a conundrum! It means it is good to plan but ultimately our plans are meaningless. In fact, our plans are a way of giving certainty to what can never be achieved. 

We do not have time, we are time. Our desire for certainty is not something we can choose. What we ultimately achieve is all down to chance. The outcome is outside of our control. We should therefore enter tasks with the mindset of not really caring what happens in the end. 

Live for today

We all know we have a finite amount of time. So why do the groundwork for the future, when the future might not even come, and our plans are no better than chance. We should stop living for the future and focus on the now. We shouldn't study for a degree just to get somewhere in the future. We should do it because in the here and now it brings us to life and determines who we are. What happens in the future is then of no consequence.

 We should treat every moment as if it is the last time, we get to do something. 

Conclusion

In the end what you do with your life doesn't really matter. You can be sure the universe doesn't care one single bit. Every life is ordinary, and this is good to remember when we feel things are getting too much for us. We can use this thought as a kind of therapy to keep us sane when we face the constant onslaught for our time and focus.

 Focus on the things you can do now and only on the things you can do now. Finitude is the only problem we have when you think about it. Just focus on the next thing you must do right now. We don't need security we just need to focus on the few things that count right now.

What is ‘e’

Just like pie, ‘e’ is widespread in mathematics and shows up in many different places. In this post I want to explore a little about what ‘e’ is and look at how you might draw a graphical representation of it using the R programming language.

Try this.

Before we begin exploring ‘e’ try this simple exercise using a calculator:
1. Enter a memorable 7-digit number on your calculator.
2. Take the reciprocal of that number, by pressing the 1/x button.
3. Add 1 to your answer.
4. Now raise the number to the power of the original 7-digit number.

Does your answer begin 2.718? If the answer is yes then you have found ‘e’!

What is ‘e’

$$e=lim_{n\to\infty}(1+\frac{1}{n})^{n}$$ We define ‘e’ to be the number that $(1+\frac{1}{n})^{n}$ is getting closer and closer to as ‘n’ gets larger and larger. $$ e=2.718281828459045... $$ If we replace 1/n with x/n we get the following equation: $$e^{n}=lim_{n\to\infty}(1+\frac{x}{n})^{n}$$ This formula $e^{n} $ has lots of interesting properties and applications.

R code to Plot ‘e’

With the simple programme below, we can show you what the growth of $e^{n}$ looks like.

x <- seq(-5, 5, by = 0.1)
y <- exp(x)
plot(x, y, type = "l", xlab = "x", ylab = "e^x")

This produces the following graph:

$$lim_{n\to\infty} e^{n}=\infty \\ lim_{n\to-\infty} e^{n}=0 \\ lim_{n\to0} e^{n}= 1 $$ The graph shows at minus Infinity the y axis approaches 0 and at Infinity the y axis approaches Infinity. But the y axis always passes through a value of 1 when x is 0.

R code to Plot inverse ‘e’

We can also plot the graph for the inverse of ‘e’ as follows:

x <- seq(-5, 5, by = 0.1)
y <- exp(-x)
plot(x, y, type = "l", xlab = "x", ylab = "e^-x")

$$ lim_{n\to\infty} e^{n}= 0\\ lim_{n\to-\infty} e^{n}= \infty \\ lim_{n\to0} e^{n}= 1$$

Creating a Ramp Generator

Have you ever wondered how to use the fact that a capacitor charges in a straight line to build a useful circuit? One simple and effective way is to turn it into a ramp generator. In this post, we'll take a closer look at how this can be achieved with a circuit that produces an output waveform that ramps up and down in a controlled manner.

The circuit consists of three main blocks: a capacitor (C1), a constant current source based on a PnP transistor, and a discharge circuit based on a FET. Let's take a closer look at how each of these components works together to create the ramp generator.

Discharge Circuit

Starting from the left side of the circuit, we have some kind of square wave oscillator producing a 1KHz pulse. The square waveform is then fed into a differentiator, which removes any DC offset and produces an output proportional to the rate of change of the signal. This means we only get an output of the rising and falling edges.

However, to ensure the circuit works correctly, we need to remove the negative side of the pulses. This can be achieved using a diode clamp, which is then fed into the gate of a FET. The FET effectively places a low resistance across the capacitor every 1ms, quickly discharging the capacitor.

Constant Current Source

A capacitor will create a linear voltage if charged from a constant current source. The circuit we're using here creates a constant current source by using a PnP transistor. For more details on how the constant current source works, please see a previous blog post on Building a Constant Current Source for Linear Charging.

By combining the discharge circuit and the constant current source, we can create a ramp generator that produces an output waveform that ramps up and down in a controlled manner. The ramp can be adjusted by changing the values of the capacitor or the constant current source.

In conclusion, by using the fact that a capacitor charges in a straight line, we can create a simple and effective ramp generator. This circuit can be useful in a variety of applications, such as in audio circuits, waveform generators, and more.

Building a Constant Current Source for Linear Charging

In a previous post (Charging a capacitor exponentially), we explored a simple circuit for charging a capacitor over a period of 1 millisecond. As we saw, the voltage against time characteristics of this circuit were exponential in nature. However, what if you want to charge the capacitor in a straight or linear line? Thankfully, you can achieve this by switching from a constant voltage source to a constant current source.

If you supply a constant current to a capacitor, you can calculate the time it will take to charge using the formula Vc = (I x t) / C, where Vc is the voltage across the capacitor, I is the current supplied, t is the charging time, and C is the capacitance of the capacitor.

 To achieve a linear charge, we can use the following circuit:

In this circuit, the capacitor C is charged through a constant current source, which ensures that the current flowing into the capacitor remains constant. As a result, the voltage across the capacitor increases linearly with time.

If you want to charge a capacitor with a constant current, you can use a constant current source. One way to build a constant current source is to use a PNP transistor.

The circuit shown above can produce a constant current of 1mA through R4. To calculate the value of the constant current, we need to determine the base voltage, Vb, which is set by the potential divider R1 and R2. Once we know the base voltage, we can easily calculate the constant current using the formula (V1 - Vb - 0.7) / R3, where V1 is the voltage supplied to the circuit, and 0.7V is the voltage drop across the emitter of the transistor.

In conclusion, a PNP transistor-based constant current source is a simple and effective way to generate a constant current for charging capacitors or driving LEDs. With some basic knowledge of transistor operation and circuit theory, you can easily design and build a constant current source that meets your requirements.
