This kind of Van de Graaff generator is made up of:
• A motor
• Two rollers
• A belt
• Two brush assemblies
• An output terminal (usually a metal or aluminum sphere)
The strong negative charge from the roller now begins to do two things:
1. It repels the electrons near the tips of the lower brush assembly.
2. It begins to strip nearby air molecules of their electrons.
Applications:
1. It is used to generate x-rays, which is widely used in medicine field.
2. It is used in atom smasher’s, which is used in research purposes.
3. It found applications in physics, medicine, and astro physics.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Electrostatics 2
1.
2. Electric Field: Electric field is a region of space around a charge or a system of charges within which other charged particles experience electrostatic forces. Theoretically, electric field extends upto infinity but practically it is limited to a certain distance. Electric Field Strength or Electric Field Intensity or Electric Field: Electric field strength at a point in an electric field is the electrostatic force per unit positive charge acting on a vanishingly small positive test charge placed at that point. The test charge is considered to be vanishingly small because its presence should not alter the configuration of the charge(s) and thus the electric field which is intended to be measured. or or + q 0 + q 0 + q - q q – Source charge, q 0 – Test charge, F – Force & E - Field E = ∆ q F Lt ∆ q -> 0 q 0 F E = q r 2 1 4 π ε 0 E = r F F

4. Electric Field due to a Point Charge: O Z Y X Force exerted on q 0 by q is P (x,y,z) Electric field strength is or or The electric field due to a point charge has spherical symmetry. If q > 0, then the field is radially outwards. If q < 0, then the field is radially inwards. 0 + q 0 + q F r q q 0 r 2 1 4 π ε 0 r F = q q 0 r 3 1 4 π ε 0 r F = q 0 F E = q r 3 1 4 π ε 0 E (r) = r r 2 1 4 π ε 0 E (r) = q r E r 2
5. Electric field in terms of co-ordinates is given by Superposition Principle: The electrostatic force experienced by a charge due to other charges is the vector sum of electrostatic forces due to these other charges as if they are existing individually. In the present example, a = 1 and b = 2 to 5. If the force is to be found on 2 nd charge, then a = 2 and b = 1 and 3 to 5. ( x 2 + y 2 + z 2 ) 3/2 1 4 π ε 0 E (r) = q i j k ( x + y + z ) + q 2 - q 3 - q 5 + q 4 + q 1 F 12 F 14 F 15 F 13 F 1 = F 12 + F 13 + F 14 + F 15 F 12 F 14 F 15 F 13 F 1 q a q b 1 4 π ε 0 F a (r a ) = ∑ b=1 b ≠a N r a - r b r a - r b │ │ 3
6. Superposition principle holds good for electric field also. Note: The interactions must be on the charge which is to be studied due to other charges. The charge on which the influence due to other charges is to be found is assumed to be floating charge and others are rigidly fixed. For eg. 1 st charge (floating) is repelled away by q 2 and q 4 and attracted towards q 3 and q 5 . The interactions between the other charges (among themselves) must be ignored. i.e. F 23 , F 24 , F 25 , F 34 , F 35 and F 45 are ignored. Electric Lines of Force: An electric line of force is an imaginary straight or curved path along which a unit positive charge is supposed to move when free to do so in an electric field. Electric lines of force do not physically exist but they represent real situations. Electric Lines of Force E E

12. Electric Dipole: Electric dipole is a pair of equal and opposite charges separated by a very small distance. The electric field produced by a dipole is known as dipole field. Electric dipole moment is a vector quantity used to measure the strength of an electric dipole. + q - q The magnitude of electric dipole moment is the product of magnitude of either charge and the distance between the two charges. The direction is from negative to positive charge. The SI unit of ‘p’ is ‘coulomb metre (C m)’. Note: An ideal dipole is the dipole in which the charge becomes larger and larger and the separation becomes smaller and smaller. 2 l p p = ( q x 2 l) l
13. Electric Field Intensity due to an Electric Dipole: i) At a point on the axial line: Resultant electric field intensity at the point P is If l << x, then The direction of electric field intensity at a point on the axial line due to a dipole is always along the direction of the dipole moment. E P = E B - E A + q - q A B E P = E A + E B The vectors E A and E B are collinear and opposite. 1 4 π ε 0 i E A = q (x + l ) 2 q (x - l ) 2 1 4 π ε 0 i E B = │ E P │ = │ E B │ - │ E A │ │ E P │ = q (x + l ) 2 q (x - l ) 2 1 4 π ε 0 ] [ - │ E P │ = 1 4 π ε 0 2 ( q . 2 l ) x (x 2 – l 2 ) 2 │ E P │ = 1 4 π ε 0 2 p x (x 2 – l 2 ) 2 E P ≈ 2 p 4 π ε 0 x 3 l l x P p E A E B O E P = 1 4 π ε 0 2 p x (x 2 – l 2 ) 2 i
14. + q - q A B Resultant electric field intensity at the point Q is ii) At a point on the equatorial line: E A cos θ E B cos θ E B sin θ E A sin θ The vectors E A sin θ and E B sin θ are opposite to each other and hence cancel out. The vectors E A cos θ and E B cos θ are acting along the same direction and hence add up. E Q = E A cos θ + E B cos θ θ θ l l y θ θ p E B E A E Q Q E Q = E A + E B The vectors E A and E B are acting at an angle 2 θ . q ( x 2 + l 2 ) 1 4 π ε 0 E A = i q 1 4 π ε 0 E B = i ( x 2 + l 2 ) E B E A E Q θ θ E Q = q 2 4 π ε 0 ( x 2 + l 2 ) l ( x 2 + l 2 ) ½ 1 E Q = 4 π ε 0 q . 2 l ( x 2 + l 2 ) 3/2 E Q = 1 4 π ε 0 p ( x 2 + l 2 ) 3/2 Q O
15. If l << y, then The direction of electric field intensity at a point on the equatorial line due to a dipole is parallel and opposite to the direction of the dipole moment. If the observation point is far away or when the dipole is very short, then the electric field intensity at a point on the axial line is double the electric field intensity at a point on the equatorial line. i.e. If l << x and l << y, then E P = 2 E Q E Q = 1 4 π ε 0 p ( x 2 + l 2 ) 3/2 (- i ) E Q ≈ p 4 π ε 0 y 3
16. Torque on an Electric Dipole in a Uniform Electric Field: The forces of magnitude pE act opposite to each other and hence net force acting on the dipole due to external uniform electric field is zero. So, there is no translational motion of the dipole . However the forces are along different lines of action and constitute a couple . Hence the dipole will rotate and experience torque . t = q E (2 l sin θ ) = p E sin θ + q - q 2 l Case i: If θ = 0 ° , then t = 0. Case ii: If θ = 90 ° , then t = pE (maximum value). Case iii: If θ = 180°, then t = 0. θ Torque = Electric Force x distance θ q E q E E t p E Direction of Torque is perpendicular and into the plane containing p and E . SI unit of torque is newton metre (Nm). t = p x E p
17. Work done on an Electric Dipole in Uniform Electric Field: dW = t d θ = p E sin θ d θ W = ∫ p E sin θ d θ W = p E (cos θ 1 - cos θ 2 ) If Potential Energy is arbitrarily taken zero when the dipole is at 90 °, then P.E in rotating the dipole and inclining it at an angle θ is Potential Energy U = - p E cos θ Note: Potential Energy can be taken zero arbitrarily at any position of the dipole. - q 2 l + q When an electric dipole is placed in a uniform electric field, it experiences torque and tends to allign in such a way to attain stable equilibrium. Case i: If θ = 0 ° , then U = - pE (Stable Equilibrium) Case ii: If θ = 90 ° , then U = 0 Case iii: If θ = 180°, then U = pE (Unstable Equilibrium) END θ 1 θ 2 q E E θ 1 θ 2 q E q E q E d θ
