The Davidson Institute at the Weizmann Institute is playing a huge role in advancing an appreciation for the study of science
By BERNIE BELLAN Dr. Liat Ben-David is a scientist who has devoted a good part of her life to educating people about science.
Having graduated with a degree in Molecular Biology from the Weizmann Institute of Science in Rehovot, Israel, in 1991, for the past seven years Dr. Ben-David has been CEO of the Davidson Institute, which is the educational arm of the Weizmann Institute.
A fourth-generation sabra, Dr. Ben-David speaks flawless English without a trace of a Hebrew accent, although I made the mistake of asking her whether she was originally from the US since, if she hadn’t corrected me, I would have sworn she was either American or Canadian-born.
Dr. Ben-David was in Canada recently to speak at an event in Toronto sponsored by the Weizmann Institute focusing on the power of science education to help foster resiliency in children and youth. She took time out from her busy schedule to participate in a Zoom call during which she explained what the Davidson Institute is all about – and how science education has come to play an even more important role in the lives of many Israelis over the past 11 months than it had previously.
To begin with, here is some information about the Davidson Institute taken from the Weizmann Institute website: “The Davidson Institute of Science Education is a non-profit organization that serves as the educational arm of the Weizmann Institute of Science. We believe in connecting people to science, and therefore we initiate, organize and operate a wide range of educational programs. We strive to be a professional epicenter for students, parents and the general public, as well as for teachers and academics, in both government and education.”
“We create activities for all sectors of Israeli society,” Dr. Ben-David explained. Not only is “science education part of our mission,” she continued, “we believe it is part of our responsibility to create a more logical society for everyone.”
There are “three components of scientific literacy” that the Davidson Institute promotes, Dr. Ben-David said: “knowledge, skills, and values.”
“You have to know which values you want to strengthen,” she noted, “so we can help make better lives.”
To that end, the Davidson Institute has made inroads into all facets of Israeli society. “We try to engage everyone in Israel,” Dr. Ben-David says. “We work in both Hebrew and Arabic.”
The Weizmann Institute -and through its education arm, the Davidson Institute, is involved in practically all areas of scientific endeavour. If you look at the Davidson Institute website (https://davidson.weizmann.ac.il/en) you will find articles on a dizzying range of subjects – from spacewalks to head surgeries in Ancient Egypt, to childhood mental disorders and so on, all written in an easy-to-understand English. You won’t be intimidated into thinking this is way too academic to understand.
The goal of the Davidson Institute is to inspire people to view science as a relevant part of their lives, Dr. Ben-David said. Educators from the institute go out to even the most remote communities in Israel, as well as make deliberate efforts to target “at-risk youths.”
Our goal is to “build esteem and self-confidence” within those young people, she explained, many of whom have dropped out of school.
While not all of them will succeed, the Davidson Institute has had a “40% success rate” in getting those drop-outs to return to school, Dr. Ben-David added.
“Science is a healing tool,” she observed.
Now, more than ever, since life in Israel has been so disrupted as a result of everything that has happened since October 7, educators from the Davidson Institute have been dealing with new challenges.
“During the past year, unfortunately, we have found ourselves working with displaced families” who have had to leave their homes” as a result of the Hamas attacks of Oct. 7th on the south as well as the attacks posed by Hezbollah in the north, Dr. Ben-David observed. “We are giving them some sense of normality and stability.”
For instance, she noted that “we’ve created seminars at Davidson” where students who have been displaced from their home schools “are given a week where we give them a full blast of science.”
“They work on science projects that are included in matriculation,” Dr. Ben-David explained.
And, educators going out from Davidson aren’t only working with high school students. “We work with kids in elementary schools age 10 and up,” she said, “also with their teachers.”
Those teachers may not have a particular background in science, Dr. Ben-David explained.
Davidson educators also don’t restrict their attention to trained teachers.
“We work with instructors who are not professional teachers on giving them instruction in science,” she noted.
I asked Dr. Ben-David to give me an example in which someone from Davidson has reached out to a child who has been traumatized by what has been happening in Israel since October 7.
She told me of one particular young girl who had been so afraid that she was going to be killed by a missile that she spent the better part of her day hiding under her bed.
Educators from Davidson came to visit the child and found out that she loved Harry Potter books. They “discussed with her the science of Harry Potter magic,” and whether there was something that might actually be plausible about some of the magic.
“At first she just peeked out at us,” Dr. Ben-David continued, “then she started asking questions” – and soon she was fully engaged in talking with the instructors.
The Davidson Institute runs several programs that aim to attract students, both from within Israel and beyond.
For instance, Dr. Ben-David pointed to a “gap year program,” now in its sixth year of existence – for high school graduates where Davidson sends them to remote communities as “science ambassadors.”
And, including during this past year, Davidson also has “several international programs” for students “from all over the world,” she explained. Not only do those students get to do science, “they get to know Israel and each other,” Dr. Ben-David said.
There are still many online programs for students, she noted, including one called “Windows to the Future,” in which “once a month students from all over the world meet a Davidson scientist” online.
“Some countries have approached us to develop different pedagogies,” Dr. Ben-David said. “Covid didn’t stop us; neither did the war.”
I wondered though, whether the trend toward academic boycotts of Israeli institutions of higher learning and, concomitantly, Israeli academics, has had a very adverse effect on Davidson Institute programs that reach out beyond Israel.
“We don’t ignore the elephant in the room,” Dr. Ben-David admitted but, in addition to the “100,000 participants” Davidson Institute programs have in Israel itself – in partnership with most municipalities, we reach another “3 million” from Israel and outside digitally, she said.
While Israel’s image in much of the world has suffered greatly as a result of its war in Gaza, Israel’s reputation as a scientific powerhouse has not diminished – and institutions like the Davidson Institute are serving to maintain that image throughout the world.

Hacker and Fraud Prevention for Online Gambling Profiles
Safeguard your online casino & sports betting accounts from cyber threats
Follow these 10 vital steps to reinforce your online gambling profile by enabling two-factor authentication, using VPNs, unique passwords and more.
With the global online gambling market projected to reach over $100 billion by 2026, securing your online casino and sportsbook accounts is more critical than ever. As digital wallets swell with winnings so too does the motivation for cybercriminals to steal credentials and loot accounts.
#1. Activate Two-Factor Authentication
Topping the list is two-factor authentication (2FA) – requiring two credentials to login instead of one at FanDuel. Often this entails providing your password plus a one-time code sent via SMS or email.
Per an Oracle study, implementing 2FA would have thwarted 99% of historical cyber attacks that involved stolen credentials.
Most regulated online gambling sites offer 2FA, accessible under account settings. Turn it on immediately for stronger defense.
#2. Never Reuse or Recycle Passwords
A cardinal sin is recycling the same password across multiple sites or services. Once one account is breached, cyber thieves can access more accounts using that same password.
To avoid this, every account deserves a unique, strong password. For simplicity, utilize a password manager app to randomly generate and store site-specific passwords.
#3. Install a VPN for Public Wi-Fi Access
When playing online casino games on shared/open wireless networks, your data flows openly and risks interception. That’s where virtual private networks (VPNs) come in.
VPNs encrypt all network traffic to and from your device. This protects your gambling activity and account credentials from Wi-Fi eavesdroppers. VPNs also disguise your IP address.
Some top-rated services include NordVPN, ExpressVPN and CyberGhost.
#4. Keep Software Updated & Run Anti-Virus Scans
You must keep computers and mobile devices updated with the latest OS and security patches. Postponing critical updates leaves open dangerous holes that malware exploits.
Likewise run reputable anti-virus scans to catch viruses attempting to infiltrate systems and spy on login credentials for financial accounts.
#5. Verify the Security & Encryption of Sites
When signing up at online betting sites and casinos, verify the legitimacy of their security measures:
- Confirm the address starts with HTTPS, not HTTP
- Check that data transmissions are encrypted using at least 128-bit SSL
- Ensure site has proper licensing
- Review privacy policy for data storage and sharing
Reputable sites will display trust badges from companies like Norton and TrustE.
#6. Avoid Account Sharing
While tempting to give friends or relatives access to funded accounts, sharing login credentials is extremely risky. You lose control over deposits/withdrawals while exposing yourself to potential theft.
Instead, gift deposits to other player accounts or refer them to open their own secure accounts.
#7. Beware Account Takeover Scams
Exercise caution if contacted unexpectedly about unusual account activity. Savvy scammers will pretend a breach occurred to trick you into handing over your username and password.
If concerned about account integrity, directly access the site yourself and contact customer support – don’t click any links in unsolicited emails.
#8. Monitor Financial Statements
Carefully review online betting account and credit card statements to detect unauthorized transactions right away. Dispute unrecognized activity ASAP to limit losses.
For further vigilance, some banks offer real-time purchase alerts via email or SMS.
#9. Don’t Save Payment Info
Saving credit card or e-wallet details on gambling sites for faster future deposits also expedites withdrawals – by you and potentially hackers.
Instead, manually enter payment info each time to contain potential damage from any account infiltration.
#10. Create a Secure Email
A strong yet oft-overlooked defense is creating a secure email account strictly for gambling transactions. Keep it completely separate from your personal email to isolate threats.
Use a nickname, enable 2FA and establish a strong password using special characters, numbers, case changes and 15+ letters.
Table: Comparison of Top VPNs for Online Gambling Site Security
| VPN Service | Encryption Standard | Number of Server Locations | Allows P2P Traffic | Number of Simultaneous Connections | Money Back Guarantee |
| NordVPN | AES 256-bit | 5400+ | Yes | 6 | 30 days |
| ExpressVPN | AES 256-bit | 3000+ | Yes | 5 | 30 days |
| CyberGhost | AES 256-bit | 7400+ | Yes | 7 | 45 days |
Fortify Your Online Gambling Fortress
As online casinos and sportsbooks explode in popularity, no player is immune to the growing plague of cyber fraud and account theft.
Guard your profile by enabling two-factor authentication, setting strong passwords, installing critical software updates and more. Also research site security measures and payment options.

Vital Role of True Randomness in Modern Computing
The critical need for true randomness in cryptography, simulations, and more
True randomness is essential for encryption, statistical sampling, simulations, and more computing applications to work effectively. We explore why.
The concept of randomness often evokes thoughts of unpredictability and chance occurrences. However in the world of computing, having access to true randomness is vital for many critical applications to function properly. Without the ability to generate random values and data, key aspects of modern technology simply would not work reliably.
In this article, we will explore what constitutes true randomness from a computational perspective, why it is crucially important, and some of the ways that software and hardware attempt to produce randomness reliably. Gaining insight into this topic highlights the dependence much of digital functionality has on the availability of non-deterministic, uniformly distributed random data.
What Makes Randomness “True”?
For data to be considered truly random from an information theory perspective, values must satisfy key mathematical and statistical qualities, for example at Lucky Seven Casino. True randomness implies meeting three core criteria:
- Uniform distribution — All potential values have an equal probability of occurring so that no bias exists towards certain numbers.
- Independence — The value at any position does not relate to or depends on values at other positions. Previous numbers do not influence future ones.
- Unpredictability — Knowing some values provides no useful information to predict other values. Guessing upcoming numbers is mathematically impossible.
Hence, true randomness requires generated data featuring high entropy (information density) with no observable patterns or correlations over any length or time period analyzed. Values must pass various statisticatests of randomness to qualify. True randomness exists only in specific natural phenomena scientists believe exhibit fundamental uncertainty such as radioactive decay. Computational methods can attempt to produce randomness but technically generate only an approximation usually called pseudo-randomness. However for many practical purposes, computationally generated randomness proves sufficient if it passes robust statistical testing.
Why True Randomness Matters Cryptography
Arguably, the area with the most crucial dependence on true randomness is cryptography. All modern encryption technologies require random number generation to ensure security. Encryption systems work by utilizing random numbers for:
- Key generation
- Initialization vectors
- Salts
- Nonces
- Padding
Any bias, predictability or correlation within random values used for the above purposes significantly compromises encryption protocols and introduces vulnerabilities. With trillions of dollars transferred online daily and vast amounts of sensitive data stored digitally, safeguarding cryptography requires high-quality random number generation rooted in solid entropy sources.
Simulations & Modeling
Outside of security, many more computing applications need randomness to operate correctly per their design intent. Monte Carlo simulations extensively utilize randomness to model complex real-world behaviors by running many iterations with differing random inputs. Financial analysis, climate modeling, nuclear reactions and molecular behavior represent common Monte Carlo simulation applications.
Games, Artificial Intelligence & Machine Learning
Gaming, AI and ML commonly incorporate randomness to increase variation, introduce unpredictability, and improve realism. For example, non-player characters in video games use randomness for movement, dialog and behavior to feel more lifelike and less robotic. AI/ML leverage randomness to train networks more thoroughly against a wider possibility space and build more resilient models less prone to biases.
Generating True Randomness via Hardware
Given the pervasive need for genuine randomness across computing, how do software and hardware reliably produce it? Most systems today use either specialized hardware random number generators or hybrid combinations of hardware and software.
Hardware options utilize the inherent randomness within low-level physical phenomena to produce entropy. Different techniques for generating randomness exist but most hardware implementations focus on three main sources:
- Thermal Noise
- Semiconductor Quantum Physics
- Chaotic Oscillator Outputs
| Generator Type | Description |
| Thermal Noise | Amplifies and extracts random electrical noise from resistor thermal vibrations |
| Quantum Physics | Leverages quantum mechanical properties like photon emission timing from LEDs/lasers |
| Chaotic Circuits | Uses unpredictable oscillator circuit outputs from chaos theory |
Semiconductor-based solutions can generate high bitrates up to 5Gbps using compact modern chip fabrication allowing extensive harvestingof entropy. However these sources derive from complex, random physical processes proving impossible to predict or fully model mathematically. This unpredictability provides excellent entropy quality unattainable via software algorithms alone.
Most general-purpose computers now integrate random number generators within CPUs allowing applications access to decent hardware-based random data. For the highest security use cases, dedicated standalone hardware random number generators exist exceeding >100Gbps speeds. Hence accessing genuine randomness is available today even on common computing devices.
Cryptographically Secure Pseudo-Random Number Generators
While hardware mechanisms utilize hard-to-predict physical phenomena to produce randomness, software solutions must take a different approach. Algorithmically-generated randomness cannot achieve true randomness from a physics perspective. However clever mathematical techniques like cyclical algorithms can generate randomness passing many statistical tests of randomness within their output bit length limits.
Cryptographically secure pseudo-random number generators (CSPRNG) serve as the premier software-based method for generating randomness. CSPRNGs work by repeatedly applying cryptographic primitives like hash or cipher functions on initial random seed values. This process produces a chain of output bits not reproducible without the original seed key. Leading CSPRNG algorithms include:
- Hash_DRBG
- HMAC_DRBG
- CTR_DRBG
Software libraries implement these CSPRNGs so developers can integrate quality randomness into applications with proper seeding. Seeding establishes the initial starting point for randomness generation using an entropy source like hardware random number generators or timing variability.
CSPRNGs allow the production of vast quantities of randomized data for any purpose needed. Compared to hardware mechanisms limited by physics on maximum speeds, algorithms scale boundlessly in the bits created as long as adequate computational power exists.
Yet key differences between software and hardware randomness remain. While CSPRNG outputs pass statistical testing and contain no observable patterns, their pseudo-randomness means given the same seed, the exact same value sequence will generate each time. Also, if a CSPRNG algorithm or implementation has flaws, adversaries could predict and exploit output resulting in compromised security. Still, with proper cryptographic design and regular reseeding, CSPRNGs provide quality randomness for most software needs.
Conclusion
From the above exploration, we see true randomness plays a pivotal role across computing – from cybersecurity to simulations and beyond. While no substitutes for true physically-derived entropy exist, modern hardware and hybrid hardware-software solutions provide abundant randomness for practical usage.
However as computing continues evolving with new technologies like quantum, ensuring high-quality randomness generation tackles emerging information security and system reliability challenges. Access to ample true randomness stands necessary now for current computing functionality and lays the foundation for future innovation.
