Ting and the J/psi Particle yield Charm quark plus 1976 Nobel Prize


While conducting research in the early 1970s at Brookhaven National Laboratory, Samuel C.C. Ting concluded he had evidence of a new elementary particle three times heavier than a proton and much longer-lived than anything physics currently knew of (where “long life” is often measured in minute fractions of a second). Ting announced his discovery of the “J particle” at about the same time Burton Richter at Stanford University demonstrated the existence of the “psi particle.” Richter went on to serve as Director of the DOE Stanford Linear Accelerator Center from 1984-1999. Their dual discoveries provided the first experimental evidence for a fourth quark, “charm,” and earned them the 1976 Nobel Prize in Physics.

ST06-004: Avoiding the Pitfalls of Online Trading

Original release date: April 07, 2011 | Last revised: February 06, 2013

Online trading can be an easy, cost-effective way to manage investments. However, online investors are often targets of scams, so take precautions to ensure that you do not become a victim.

What is online trading?

Online trading allows you to conduct investment transactions over the internet. The accessibility of the internet makes it possible for you to research and invest in opportunities from any location at any time. It also reduces the amount of resources (time, effort, and money) you have to devote to managing these accounts and transactions.

What are the risks?

Recognizing the importance of safeguarding your money, legitimate brokerages take steps to ensure that their transactions are secure. However, online brokerages and the investors who use them are appealing targets for attackers. The amount of financial information in a brokerage’s database makes it valuable; this information can be traded or sold for personal profit. Also, because money is regularly transferred through these accounts, malicious activity may not be noticed immediately. To gain access to these databases, attackers may use Trojan horses or other types of malicious code (see Why is Cyber Security a Problem? for more information).

Attackers may also attempt to collect financial information by targeting the current or potential investors directly. These attempts may take the form of social engineering or phishing attacks (see Avoiding Social Engineering and Phishing Attacks for more information). With methods that include setting up fraudulent investment opportunities or redirecting users to malicious sites that appear to be legitimate, attackers try to convince you to provide them with financial information that they can then use or sell. If you have been victimized, both your money and your identity may be at risk (see Preventing and Responding to Identity Theft for more information).

How can you protect yourself?

  • Research your investment opportunities – Take advantage of resources such as the U.S. Securities and Exchange Commission’s EDGAR database and your state’s securities commission (found through the North American Securities Administrators Association) to investigate companies.
  • Be wary of online information – Anyone can publish information on the internet, so try to verify any online research through other methods before investing any money. Also be cautious of “hot” investment opportunities advertised online or in email.
  • Check privacy policies – Before providing personal or financial information, check the website’s privacy policy. Make sure you understand how your information will be stored and used (see Protecting Your Privacy for more information).
  • Conduct transactions on devices you control – Avoid conducting transactions on public resources such as internet kiosks, computers in places like libraries, and other shared computers and devices. Other users may introduce security risks.
  • Make sure that your transactions are encrypted – When information is sent over the internet, attackers may be able to intercept it. Encryption prevents the attackers from being able to view the information.
  • Verify that the website is legitimate – Attackers may redirect you to a malicious website that looks identical to a legitimate one. They then convince you to submit your personal and financial information, which they use for their own gain. Check the website’s certificate to make sure it is legitimate (see Understanding Web Site Certificates for more information).
  • Monitor your investments – Regularly check your accounts for any unusual activity. Report unauthorized transactions immediately.
  • Use strong passwords – Protect your computer, mobile devices, and accounts with passwords that cannot easily be guessed (see Choosing and Protecting Passwords for more information). Use different passwords for each account.
  • Use and maintain anti-virus software – Anti-virus software recognizes and protects your computer against most known viruses. However, because attackers are continually writing new viruses, it is important to keep your virus definitions current (see Understanding Anti-Virus Software for more information).
  • Use anti-spyware tools – Spyware is a common source of viruses, and attackers may use it to access information on your computer. You can minimize the number of infections by using a legitimate program that identifies and removes spyware (see Recognizing and Avoiding Spyware for more information).
  • Keep software up to date – Install software updates so that attackers can’t take advantage of known problems or vulnerabilities (see Understanding Patches for more information). Enable automatic updates if the option is available.
  • Evaluate your security settings – By adjusting the security settings in your browser, you may limit your risk of certain attacks (see Evaluating Your Web Browser’s Security Settings for more information).
