##### Introduction:

China, known for its rapid industrialization and economic growth, has been grappling with severe air pollution for decades. However, recent efforts and measures implemented by the Chinese government have shown some promising results in the battle against air pollution. Although progress has been made, there is still much work to be done to achieve sustainable and clean air for all Chinese citizens.

The Struggle with Air Pollution:
China's struggle with air pollution has been primarily attributed to its heavy reliance on coal-fired power plants, industrial emissions, vehicle exhaust, and rampant construction activities. The situation reached alarming levels in major cities, such as Beijing and Shanghai, where smog-filled skies became a common sight, posing significant risks to public health and the environment.

Government Actions and Policies:
Recognizing the urgency of the situation, the Chinese government launched a series of measures to combat air pollution. In 2013, it implemented an ambitious action plan known as the "Air Pollution Prevention and Control Action Plan." The plan aimed to reduce particulate matter (PM) concentrations and improve air quality by setting specific targets and implementing stricter regulations.

One of the key strategies adopted by the government was the promotion of clean energy sources. China has become the world's largest investor in renewable energy, with massive investments in solar and wind power. By shifting away from coal and embracing cleaner energy alternatives, the government aimed to reduce the emissions responsible for air pollution.

Additionally, stricter emission standards were introduced for industries and vehicles, mandating the use of cleaner technologies and catalytic converters. The government also implemented measures to reduce dust from construction sites and to control agricultural burning, both significant contributors to air pollution.

Progress and Achievements:
The efforts to combat air pollution in China have shown positive results. According to data from the Ministry of Ecology and Environment, the average concentration of PM2.5, the most harmful airborne particles, has decreased by more than 30% in major cities since 2013. This reduction in particulate matter levels has contributed to improved visibility and healthier air for millions of people.

Furthermore, the transition to cleaner energy sources has made significant strides. China has become a global leader in renewable energy capacity, with its solar and wind power sectors experiencing exponential growth. This shift has not only helped reduce air pollution but has also positioned China as a major player in the fight against climate change.

Even the best amplifiers in the world (and ours is not) can be susceptible to electromagnetic noise. You've got your killer experiment designed, your preparation and electrode in place, but BLAST! where is that infernal noise coming from that's drowning out your spikes? You can thank Nikola Tesla for your electrical noise, but, have no fear, Michael Faraday has come to your rescue!

## What will you learn?

In the lesson you will learn exactly what makes electromagnetic interference (EMIs) and how they interfere with your recordings. You will also learn how a faraday cage helps shield your recordings from (EMIs). Finally you will build your very own faraday cage and enlist in the battle against noisy data!

## Background

A Faraday cage is a container made of conducting material, such as wire mesh or metal plates, that shields what it encloses from external electric fields. In our experiments, a Faraday cage can be used to prevent external electromagnetic interference (EMI, or noise) from interfering with our neural recordings. As you know, the neural signals that we are recording are very small (on the order of micro-volts), and we use our Spikerboxes to amplify these small signals to a large enough amplitude that we can hear and record them. Depending on our environment, though, there can be electromagnetic, radio, microwave, or other types of invisible emissions that can travel through the air and interact with the metal needles and wire that we use as electrodes. The metal then propagates the noise signal like an antenna into our neural recordings, interfering with or even drowning out our recordings so that all we hear, in the worst cases, is a radio station! A Faraday cage then can be used to block many of these noise sources.

![IMAGE ALT TEXT HERE](/images/post/post-4-1.jpeg)

The Faraday cage is named after 1800s scientist [Michael Faraday](https://en.wikipedia.org/wiki/Michael_Faraday), but to learn how the cage works we start with another famous scientist, [Charles-Augustin de Coulomb](https://en.wikipedia.org/wiki/Charles-Augustin_de_Coulomb). Coulomb did much work on the dynamics of charged particles and the electric fields that they generate. Coulomb determined that the electric field, "E", at a radius "r" away from a stationary point charge, "Q", could be calculated by this equation:

![IMAGE ALT TEXT HERE](/images/post/post-4-2.jpeg)

Where ε0 is the permittivity of free space and er is the radial unit vector. If you don't understand the math (you will one day), it means the electric field strength declines the further away you are from an electric source. If you are driving on a highway and notice a radio station fading, for example, it's because you are getting further away from the big radio transmitter tower.

The take-home is that this law gives us the foundation for a mathematical relationship that relates charge and electric fields within a fixed volume of space. A Faraday cage encloses such a fixed volume of space, and, if the cage is made of conductive material, the cage's defining characteristic is that it prevents external charges from inducing electric fields within that volume. Here are two of the main rules that govern this barrier effect:

1. Coulomb's Law demands that the charges in a conductor at equilibrium be as far apart as possible, and thus the net electric charge of a conductor resides entirely on its surface.
2. Any net electric field inside the conductor would cause charge to move since it is abundant and mobile, but equilibrium demands that the net force within the conductor is equal to zero. Thus, the electric field inside of the conductor is zero.
Rule 2 tells us that the electric field inside the conductor at equilibrium is zero, and Rule 1 tells us that the charge of the conductor will be found entirely at the surface (boundary). In other words, the surface of the conducting volume becomes a barrier where charges move to and around the surface to generate fields exactly opposing any charge that seeks to cross the border, thus maintaining an interior free from external electrical interference.

![IMAGE ALT TEXT HERE](/images/post/post-4-3.jpeg)

Faraday first demonstrated this in a [famous ice bucket and metal sphere experiment](https://en.wikipedia.org/wiki/Faraday's_ice_pail_experiment). Faraday lowered a metal ball charged with static electricity into a metal bucket supported by a wooden chair that insulated the bucket from the ground. When the charged ball was lowered into the bucket without touching the bucket, the charges on the surface of the bucket became redistributed through electrostatic induction. This concept became known as the Faraday cage principle you are studying today.

![IMAGE ALT TEXT HERE](/images/post/post-4-4.jpeg)

Below we will examine the effects of the Faraday cage on various conditions when doing neural recordings with the SpikerBox, along with an easy experiment you can do at home. Here is a video explaining a very simple way to build and use a Faraday Cage.

[![IMAGE ALT TEXT HERE](https://img.youtube.com/vi/FVBti1vhJVA/0.jpg)](https://www.youtube.com/watch?v=FVBti1vhJVA)

## Procedure

###### Building the Faraday Cage
Note that we also sell pre-made Faraday Cages if you do not want to visit the hardware store.

1. Measure out an 8 x 16 inch rectangle of screen metal mesh
2. Cut out the rectangle with heavy duty scissors
3. Measure and cut five 8-inch lengths of wood strips
4. Carefully unroll metal mesh rectangle so that it lays flat
5. Begin Stapling metal mesh through wood strips
6. Staple first strip at end of mesh.
7. Staple second strip 5.5 inches away from first strip, again length-wise on mesh
8. Staple third strip 2.5 inches distant from second strip
9. Staple fourth strip 5.5 inches distant from third strip
10. Staple fifth strip at far end of mesh
11. The wood strips are braces, so after stapling them into place, fold the mesh at each strip to form a rectangular box

###### Using the Faraday Cage for Spikes
1. Set up a standard cockroach leg recording prep as described in Experiment 1
2. Create a noisy environment by hooking up a laptop to wall outlet and turning on a soldering iron or other high power appliance. Place your SpikerBox by these electronics, and also turn on all fluorescent lights in the room. Record your observations on noise level vs. neural signal level.
3. Clip an alligator clip to the ground (outside of RCA connector) on the Spikerbox.
4. Place your Spikerbox into your Faraday cage, with cage open. Record your observations on noise level vs. neural signal level.
5. Close your Faraday cage but don't connect the alligator clip to anything. Record your observations on noise level vs. neural signal level
6. Connect your alligator cable to the screen mesh of the cage. Record your observations on noise level vs. neural signal level
###### Using the Faraday Cage on Cell Phones
1. Microwave ovens are examples of Faraday cages, because they are meant to prevent the radiation used to cook the food from escaping into the environment. Aluminum foil is a conductive material, which may also be used to create a quick, impromptu Faraday cage (just ask your neighborhood neuroscientist).

2. Call your cell phone and make sure that it rings (this is your control).
3. Next, take your cell phone and put it in a (turned off!) microwave.
4. Call the cell phone from another phone. Does it ring?
5. Next, open the microwave door and dial your house phone number on the cell phone. As soon as you hit 'send', shut the microwave door quickly. Does your house phone ring?
6. Finally, wrap the cell phone in aluminum foil. Call the cell phone again? Does it ring?

Are you ready to give your mathematics skills a boost? These simple math tricks can help you perform calculations more quickly and easily. They also come in handy if you want to impress your teacher, parents, or friends.

## 01 Multiplying by 6

If you multiply 6 by an even number, the answer will end with the same digit. The number in the ten's place will be half of the number in the one's place.

Example: 6 x 4 = 24.

## 02 The Answer Is 2

1. Think of a number.
2. Multiply it by 3.
3. Add 6.
4. Divide this number by 3.
5. Subtract the number from Step 1 from the answer in Step 4.
The answer is 2.

## 03 Same Three-Digit Number

1. Think of any three-digit number in which each of the digits is the same. Examples include 333, 666, 777, and 999.
2. Add up the digits.
3. Divide the three-digit number by the answer in Step 2.
The answer is 37.

## 04 Six Digits Become Three

1. Take any three-digit number and write it twice to make a six-digit number. Examples include 371371 or 552552.
2. Divide the number by 7.
3. Divide it by 11.
4. Divide it by 13.
The order in which you do the division is unimportant!

The answer is the three-digit number.

Examples: 371371 gives you 371 or 552552 gives you 552.

1. A related trick is to take any three-digit number.
2. Multiply it by 7, 11, and 13.
The result will be a six-digit number that repeats the three-digit number.

Example: 456 becomes 456456.

## 05 The 11 Rule

This is a quick way to multiply two-digit numbers by 11 in your head.

1. Separate the two digits in your mind.
2. Add the two digits together.
3. Place the number from Step 2 between the two digits. If the number from Step 2 is greater than 9, put the one's digit in the space and carry the ten's digit.
Examples: 72 x 11 = 792.

57 x 11 = 5 _ 7, but 5 + 7 = 12, so put 2 in the space and add the 1 to the 5 to get 627

## 06 Memorizing Pi

To remember the first seven digits of pi, count the number of letters in each word of the sentence:

"How I wish I could calculate pi."

This becomes 3.141592.

## 07 Contains the Digits 1, 2, 4, 5, 7, 8

1. Select a number from 1 to 6.
2. Multiply the number by 9.
3. Multiply it by 111.
4. Multiply it by 1001.
5. Divide the answer by 7.
The number will contain the digits 1, 2, 4, 5, 7, and 8. 

Example: The number 6 yields the answer 714285.

## 08 Multiply Large Numbers in Your Head

To easily multiply two double-digit numbers, use their distance from 100 to simplify the math:

1. Subtract each number from 100.
2. Add these values together.
3. 100 minus this number is the first part of the answer.
4. Multiply the digits from Step 1 to get the second part of the answer.

## 09 Super Simple Divisibility Rules

You've got 210 pieces of pizza and want to know whether or not you can split them evenly within your group. Rather than whip out the calculator, use these simple shortcuts to do the math in your head:
- Divisible by 2 if the last digit is a multiple of 2 (210).
- Divisible by 3 if the sum of the digits is divisible by 3 (522 because the digits add up to 9, which is divisible by 3).
- Divisible by 4 if the last two digits are divisible by 4 (2540 because 40 is divisible by 4).
- Divisible by 5 if the last digit is 0 or 5 (9905).
- Divisible by 6 if it passes the rules for both 2 and 3 (408).
- Divisible by 9 if the sum of the digits is divisible by 9 (6390 since 6 + 3 + 9 + 0 = 18, which is divisible by 9).
- Divisible by 10 if the number ends in a 0 (8910).
- Divisible by 12 if the rules for divisibility by 3 and 4 apply.
Example: The 210 slices of pizza may be evenly distributed into groups of 2, 3, 5, 6, 10.

## 10 Finger Multiplication Tables

Everyone knows you can count on your fingers. Did you realize you can use them for multiplication? A simple way to do the "9" multiplication table is to place both hands in front of you with fingers and thumbs extended. To multiply 9 by a number, fold down that number finger, counting from the left.

Examples: To multiply 9 by 5, fold down the fifth finger from the left. Count fingers on either side of the "fold" to get the answer. In this case, the answer is 45.

To multiply 9 times 6, fold down the sixth finger, giving an answer of 54.

10 Math Tricks That Will Blow Your Mind


A potato battery is a type of electrochemical cell. An electrochemical cell converts chemical energy into electrical energy. In the potato battery, there is a transfer of electrons between the zinc coating the galvanized nail that will be inserted into the potato and the copper wire that will be inserted another part of the potato. The potato conducts electricity, yet keeps the zinc ions and copper ions separate, so that the electrons in the copper wire are forced to move (generate current). It's not enough power to shock you, but the potato can run a small digital clock.

## 01 Materials for a Potato Clock

You may have the supplies for the potato clock lying around the house already. Otherwise, you can find the materials for a potato clock in any hardware store. There are also pre-made kits you can purchase that contain everything you need except the potatoes. You will need:

- 2 potatoes (or cut one potato in half)
- 2 short lengths of copper wire
- 2 galvanized nails (not all nails are galvanized or zinc-coated)
- 3 alligator clip wire units (alligator clips connected to each other with wire)
- 1 low-voltage LED clock (type that takes a 1-2 volt button battery)

## 02 How to Make a Potato Clock

Here is what you need to do to turn the potato into a battery and get it to work the clock:

1. If there is a battery already in the clock, remove it.
2. Insert a galvanized nail into each potato.
3. Insert a short piece of copper wire into each potato. Put the wire as far as possible from the nail.
4. Use an alligator clip to connect the copper wire of one potato to the positive (+) terminal of the clock's battery compartment.
5. Use another alligator clip to connect the nail in the other potato to the negative (-) terminal in the clock's battery compartment.
6. Use the third alligator clip to connect the nail in potato one to the copper wire in potato two.
7. Set your clock.

## 03 More Fun Things to Try

Let your imagination run with this idea. There are variations on the potato clock and other things you can try.

See what else your potato battery can power. It should be able to run a computer fan. Can it light a light bulb?
Try substituting copper pennies for the copper wire.
Potatoes are not the only foods that can act as electrochemical cells. Experiment with lemons, bananas, pickles, or cola as a power source.

In the midst of the swift advancement of automation in surgical procedures, Medicaroid Corporation has unveiled the inaugural Japanese-made surgical robot, named "Hinotori." This innovative creation is anticipated to make significant inroads into a market that has predominantly been controlled by foreign companies thus far.

## Technological Innovation in the World of Medicine

In August 2020, the new surgical robot received approval for manufacturing and sales in Japan. Later, in December 2022, additional robotic surgical procedures were approved for insurance coverage. On January 10, 2023, Hinotori, the surgical robot, was honored with the Prime Minister's Prize from the Ministry of Economy, Trade, and Industry.

> Equipped with four robotic arms, Hinotori replaces the surgeon and is operated remotely. The surgeon performs the procedure while referring to detailed 3D stereoscopic images for guidance.

Medicaroid, a joint venture between Kawasaki Heavy Industries and Sysmex Corporation, initiated the development of Hinotori in 2015. Kawasaki, known for developing Japan's first industrial robot, and Sysmex, a leader in medical testing and diagnostic technology, have combined their technological expertise for Hinotori's advancement.

By June 2022, robotic surgery had expanded its presence in various medical departments, including urology, gastrointestinal surgery, and gynecology. A total of 28 Japanese medical facilities, including university hospitals, had incorporated surgical robots. Over the following six months until December 15, 2022, Hinotori had been used in 840 surgeries.

From 1999 to 2022, the da Vinci Surgical System, developed by Intuitive Surgical, Inc. in the United States, held a near monopoly in the surgical robot market. However, after the expiration of their patent in 2019, several companies entered the market.

Hinotori, which is smaller and more affordable, with prices starting at approximately ￥ 200 million JPY ($1.56 million USD), is gaining significant traction. Medicaroid estimated in June 2022 that it would capture around 20% of the domestic market share within two years of its sales launch.
