King Wen’s Ba Gua Next, we come to ‘Ba Gua’ diagram or eight states diagram as shown above. Ok, what is message that it want to deliver to us? Usually, Chinese people will hang it on the top of the front door of their house saying that it will chase away ghost or bad luck. Really? Will it contains any mathematical concepts which explain our nature? Korean Flag Just an extra information, as we can see that the Korean Flag also having the similar symbols…... Well, not quite. 4 symbols of the Ba Gua have been taken away and the white and black dots of the Tai Ji symbol in the centre are missing.

Pu Yi’s Ba Gua South south-East south-west East West North-East North North-West In the original document of I-Ching, we can see that directions have been assigned to each of the 8 symbols. Why is that so?

Will these stars belong to this particular direction? Let us begin our discussion from a simple point of view. Please refer to the following slides.

Low Low Low Low Low High Low High Low Low High High By using 3 switches and by performing all the 8 possibilities , we will get an alternative way to understand ‘Ba Gua’ diagram. Low Low Low Low Low High Low High Low Low High High

Let High = H and Low =L H L L H L H H H L H H H

Switch C Switch C Switch B Switch B Switch A Switch A All the eight symbols in the ‘Ba Gua’ diagram consist of outer-most line, middle line and inner most line. We assume the outer-most line represent switch C, the inner-most line represent switch A and the middle line represent switch B. Remind that the original meaning of these symbols will be different from what we assume here. Remember that we are using scientific approach here.

Now, we will try to use the point of view from digital electronics as a stepping stone to understand ‘Ba Gua’ diagram. Switch C Switch B Switch A Low Low Low Let us assume that there is a room which having eight light bulbs which separately attached to the edges. We have 3 switches to control them. When we turn all the switches to the ‘Low’ state, the light bulb at the bottom left corner is turned on.

Switch C Switch B Switch A Low Low High

Switch C Switch B Switch A Low High Low

Switch C Switch A Switch B Low High High

Switch C Switch B Switch A H L L

Switch C Switch A Switch B H L H

Switch C Switch B Switch A H H L

H H H Finally, when we turn all the switches to the ‘High’ state, Switch C Switch B Switch A Finally, when we turn all the switches to the ‘High’ state, the light bulb at the bottom right corner is turned on. H H H

Reference point If we ‘float’ in the middle, we will see eight light bulbs in 8 directions. Only 1 light bulb will turn on each time.

Conclusion: We can say that each of the eight symbols in ‘Ba Guo’ diagram represent a particular direction. Switch C Switch B Switch A Low Low Low

Digital Integrated circuit Light bulb, in off state Switch A Switch B Switch C Digital Integrated circuit We can actually implement this circuit in real life situation by using a digital IC, switches, light bulbs or Light Emitting Diode and wires.

A B C Switch C Switch B Switch A We can design ( using Computer Aided Design software ) a combinational logic circuit which have 3 inputs (Switch A,B and C) and 8 outputs (which represent the 8 symbols in ‘Ba Gua’ diagram).

Switch C Switch B Switch A We connect wires from the 3 switches to the Wire C Wire A Wire B Switch C Switch B Switch A We connect wires from the 3 switches to the wire A, wire B and wire C in the circuit diagram.

A B C We connect the out, out2, out3, out4, out5,out6,out7 and out8 to 8 light bulbs which situated at the edges of the room .

Ground To make the light bulbs work, we need the ‘ground’. Switch A Switch B Switch C To make the light bulbs work, we need the ‘ground’. We assume the IC is already being powered. Ground

Switch C Switch B Switch A Low Low Low We ignored the wiring for clarity purposes. When we let switch A, B and C to be in low state, We can see that only one light bulb turn on. The others are off.

These are the timing diagrams that simulate all the 8 possibilities of Switch A Switch B Switch C These are the timing diagrams that simulate all the 8 possibilities of the switches.

These are the outputs that will control the eight light bulbs.

X Y Z 1 1 1 1 1 1 1 1 1 To further enhance our understanding, let us take a look to the I-Ching diagram again. Remember the game which shown previously? Here, X can be used to represent ‘Farmer’, Y for ‘Wild dog’ and Z for ‘Chicken’. X=0 y =0 z=0 represent all of them is at the right Side of the river bank. X =1 y=1 z=1 means that they are at the left side of the river bank.

X Y Z We can see the one to one correspondence again. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 We can see the one to one correspondence again.

X Y Z 1 1 1 1 1 1 1 1 1 We can see that the 0 0 0 and 1 1 1 are again can be related to the symbols in ‘Ba Gua diagram’

now use to represent dimensions. X Y Z 1 1 1 1 1 1 1 1 1 Y-axis X-axis Z-axis Next, instead of representing Farmer, wild dog and chicken, the X, Y and Z are now use to represent dimensions.

Let us try to relate the direction in the coordinate indicated here. X Y Z 1 1 1 1 1 1 1 1 1 Y-axis Let us try to relate the direction in the Ba Gua with the coordinate indicated here. North X-axis Z-axis

Y-axis X-axis Z-axis West South North East Now, we can also use arrows to point to the particular directions. The four arrows indicate the North, South, East and West.

Y-axis X-axis Z-axis south-East south-west North-East North-West The arrows in the square indicate North-west, North-east, South-east and South-west.

Y-axis X-axis Z-axis Combining all the arrows together indicating the directions in 3 dimensions. Remind that we are not providing definite answer here since the author had not went through the former education of I-Ching. The results of our discussion might differ with the original meaning. However, after these lengthy discussions we are able to get some clues and start to see the relation between Science and I-Ching. There is a doubt! Please refer next slide.

Logically, the north-west, north-east , south-west and south-east directions should be in the following ways as indicated by the green arrows as shown below. South-west North-west South-east X-axis North-east Z-axis

X-axis Z-axis North-west South-west South-east North-east North-west Do you see the difference of the direction of North-west in the diagrams above? Let us go through step by step to see whether there are any connection between these two diagrams.

Will these stars situated within this region? North-west X-axis Z-axis Will these stars situated within this region? Will this provide an insight to us that is the reasons why the stars are included in the ‘Luo Pan’? We have to discuss these since we will need these as a foundation to understand the exciting part 3 which discuss about quantum mechanics, fractal physics, discrete mathematics, essence of Hua Yan Buddhism and new mathematical structure for DNA and new Boolean simplification methods.
